In my subjective experience, I don't feel I fit any of the types well. However, outside observers all tell me I fit INFJ well, so I've kind of decided mbti is more useful for outsiders wanting to label other people as they see them, than it is for myself wanting to label myself. So in terms of how I come across to others, sure, I guess INFJ fits me best. But personally I have a hard time seeing Fe being my dominant in terms of decision-making. Amongst other things.
