See, if I didn't know what came next, I'd probably opt for the red. I'd really want to know the truth. I'd practically need to. It'd eat at me forever if I hadn't -- sure, I wouldn't remember meeting a bunch of cool dudes in leather and shades if I took the blue (and if I did, I'd just assume it was a craaazy night), but I would remember some events leading up to it.
If I somehow knew that taking the red pill would end up with me being unplugged from the Matrix and had to go through all of the crap that Neo went through, especially two terrible sequels, then I would have to go blue.
I like to imagine that in the casting call for the Matrix, they offered every candidate for Neo a blue and red pill. If you take the blue, you wake up home with no memory of this audition. If you take the red, you see how far we're willing to milk this franchise, and how crappy we can make sequels to a really cool movie.
