Hm... this is interesting to see what other INFJs prefer and the other types prefer.
Personally, I am absolutely weak for INTJs and INTPs, because they are so full of mystery, self-confidence, brains, and usually also brawn. Dr. Lecter, Dr. Manhattan, Data, Dr. Oliver Sacks, (Dr.) Einstein, I am sooo yours!
And oh, to date an INTJ or INTP is to feel like their most special person in the world, because they will really only show their soft side to you and no one else. <3
