If I could choose, I think I would go with ENTJ. They're prepared, organized, decisive, and intelligent in addition to being extroverted (an important bonus, if you ask me). I would also settle for ENTP.
I border between the two, so I get to experience both of those mindsets. I would love to be an ISFJ; they seem like lovely, sensitive, and wonderfully charismatic people. To be fair, my girlfriend is an ISFJ, so you could say I'm biased.
