Stop arguing to argue, people. A wise man once said, "Don't talk about things you don't understand." Grow up.
OP, I have adult ADD and have been figuring out treatment for the last two years--ultimately, what you decide is up to you. If you can still reasonably handle your responsibilities, cognitive therapy might work well for you and you might not need medication.
I don't read the literature on ADHD because I ultimately find it misinformed or formatted to sell. The most helpful things, for me, were keeping regular contact with older people who had ADHD and had been working with it themselves for a longer span of time, as well as journaling about it. I don't like to just "talk" about things, so there had to be an aim to expanding my awareness of the disorder.
As far as the pros and cons go... I feel like there are no true "pros" to having the disorder, but that could be argued by others who have it? It makes me less judgmental but it also makes me more emotional, sometimes to the point of petulance.
An MBTI board might not be the best place, oddly enough, to approach the disorder... Nobody's really interested in neuroscience, only in themselves and why they're special.
