For my part, if I could be reincarnated, I guess it would be as a woman but with an otherwise similar life. Fairest comparison possible of the different experiences between the sexes.
I'm really warmed by how happy everyone is with their lives now for the most part, I think that's a real result. I have always wanted to be Japanese, had an absolute obsession with Japanese culture when I was little, then killer anime didn't help, plus Japanese girls are exquisite, not that I'm unhappy with who I am, but it's possibly the one thing I would change.
