IRL, my favorite people to interact with are definitely 7w6s: they're a whole lot of fun, and are a lot zanier and more random than I am, which is cool because they're great at putting me in a good mood. You really, really can't help but like 7w6s, and they really, really can't help but make your day better. 7w8s are awesome to make plans with, since we tend to know exactly what we'd all like to do and how to go about it, but all the 7w8s I know (myself included) have gigantic egos which clash if there are too many of us in the same room. 7w6s are all of the fun, none of the ego, which is great. However, 7w8s will do crazier shit with you, so you can feel free to get wild and fuck shit up. Plus, the subtle power games they play can be a lot of fun (unlike with 8w7s, who are more overt, take it more seriously and don't work it into a positive atmosphere), and the fact that we share a lot of interests and the same outlook means that it's easier for me to hang out with 7w8s for a lengthy stretch of time than with 7w6s. All in all, both types of sevens are the best people to party with, since we're all focused on having fun and keeping our moods up.
I get along pretty well with 3s, since we also have a similar mindset and drive. Difference is, threes are a lot more single minded and focused than I am (focus is an understatement; 3s literally seem like they only have one thing on their minds at all times). So, I'd say 3s make awesome people to work with, and are great to have around in professional settings, but aren't as able to let loose and go crazy in a more casual environment. I get along better with 3w2s than 3w4s on a personal level, simply because 3w2s are more engaging and fun, while 3w4s are more stolid and hyper-professional. However, I find it easier to learn from 3w4s, as they like to display their competence much more, which makes it easier to replicate. With 3w4s, it's more of an "arm's distance" relationship, where we have mutual respect but are not overly friendly.
I have a love/hate relationship with 8s; we either get along really, REALLY well, and we always have the same outlook, goals, and attitude (8s just tend to be more serious versions of me), or we clash completely and can't stand each other. However, 8s remain my favorite type to do business with; absolutely no bullshit, just bottom line, "what can you offer me" frankness and openness. I get along better with 8w9s than 8w7s, since 8w7s have bigger egos and make more overt power plays, which turns into athing between us which leads to a lot of friction, while 8w9s are more content to just chill and make sure their boundaries are being respected. However, 8w7s are more tolerable and awesome to be around in smaller doses, since they're dynamic and more likely to make something interesting happen. 8w9s are the reverse; rather unassuming in small doses, but awesome to have around a lot.
Twos have a lot of irritating traits, but one of my best friends is a 2w3, so I can certainly get along really well with them. Twos can actually look like sevens if you don't know them too well; they've got the same extroversion and charm, and the same desire to be around people. However, once you get closer, the differences are obvious. I find twos to be very other directed and very, very sensitive to what people are thinking about them, while I'm more focused on my own experiences and getting what I want, and don't care about what people think unless their negative perceptions will get in the way of what I want. They try and take on a "parent" role, which is definitely irritating, much more so than 8w7 power grabs because they play an emotional game that I don't like to fuck around with unless I gain from it somehow. They are also really, really fucking delusional; they find it nearly impossible to see their role in making bad things happen to them, and consequently, take on a martyr complex that results in them not learning from their mistakes and thus, repeating them and complaining about it, which feeds into this idea, which becomes a vicious cycle. However, twos are pretty great at networking and keeping in touch with people, so it's really easy to keep them around, and it's also easy to keep in touch with mutual friends through them, without having to actually talk to them all the time. By contrast, I'm great at getting people to like me a lot and want to be around me, but I'm terrible at keeping in touch once the juice is gone and I've moved somewhere else. They're also really easy to connect with, and can become very good friends to have around.
I like nines because they're genuinely chill (Type 9 is the typical stoner, lol), but it's hard to make things happen with a lot of nines around. They're great to relax with, and are willing to let me take the lead without much fuss, but too many nines leads to very little getting done and a lot of boredom on my part.
Fours are way, way too emotionally intense for me; I like how easy it is to connect with them, but they're too comfortable with negativity and sadness, which clashes with my desire to keep the mood up and focused on making things happen. I'm naturally very solution-oriented, so hearing about bad feelings without being able to solve the problem and move on to something happier gets on my nerves. I don't mind them, but there's too much negativity for me to like being around them for very long. I'll listen to your problems, but don't come to me for sympathy or venting, come to me for solutions. You can vent all you like, of course, as long as we can get to solving the problem and moving on eventually. I'm definitely not a "feelings" guy.
Funny enough, I can't think of any clear ones or fives I know IRL, but I would guess that I'd heavily clash with ones in action, since I tend towards amorality and hedonism in my day to day life and with my goals and outlook, which is the complete opposite of how ones prefer to do things. I'd probably get along very well with both in discussions, as these types have the most philosophical tendencies, and thus, likely to provide very stimulating conversations. With ones, it'd become about ideals, while with fives, it'd be more about actualities. So, I'd have a lot of fun debating with ones over what is or isn't ideal, whether or not something is practical, and also deconstructing their ideals to the point where I'd be able to convince them to see things my way (usually, my response to people who criticize me on moral grounds is a "beyond good and evil" speech, which is always a lot of fun), while hearing some interesting counterpoints in the process. With fives, I'd have fun deconstructing the world around us and revealing its meaninglessness and/or the foolishness of society's conventions and the people who make it up. I'd probably take a more existentialist perspective, though, and say that whether it means anything or not, I may as well live by my own standards and enjoy my time to the maximum, while fives strike me as being more likely not to get past the whole "but what's the point" part of it.
It's cliché, but the people who tend to get under my skin the most often IRL are sixes. Sixes are a lot more conscientious and by-the-book than I am, and we don't see eye to eye on a lot of things. They also find it harder to just let go and enjoy themselves, and often ruin a good time by being too suspicious and prone to overreact to perceived disrespect. By contrast, eights generally just raise an eyebrow and let it defuse on its own, preferring to hint at their strength and using their assumed power to make people back down, while a six is more likely to go for a full reaction and cause it to escalate unnecessarily (I've found that eights get quieter and quieter as things go down, and get this really defiant look on their faces that pretty much just says "come at me, bro", while sixes tend to get louder and louder, constantly escalating and overreacting, or saying nothing and suddenly striking out of nowhere). They also get mad about things which I really can't bring myself to give a shit about, and then, get mad that I don't care, while I tend to say "it's not a big deal" automatically, which understandably pisses them off. The projection is a big annoyance, too, as they accuse you of bullshit and read motivations into you that you clearly don't have. Finally, they also have a victim mentality similar to twos, except that it's a persecution complex rather than a martyr one. They genuinely believe people are targeting them, so they act in ways which alienate people, which leaves them isolated and makes people target them. However, what I like about sixes is that they will go out of their way to help their friends, even more so than twos, who rationalize not helping you when it doesn't suit them by telling themselves they already do enough for everyone. Also, a determined six has the ability to rally people together like no other, because they find it easy to speak for the group and naturally pay attention to ways people are being abused and/or exploited. And hey, I was raised by a six, so clearly they did something right.
So, as far as IRL interactions go:
7w6 > 7w8 > 3w2 > 8w9 = 8w7 (at the best of times) > 9 > 2 > 3w4 > 4 > 6 > 8w7 (at the worst of times)
