As for me I would vote either NTJ or INTP. Ni sounds like it's a major pain in the butt for the user but it also seems at times from my perspective to be the key to human genius - with Ne being a more palatable alternative but falling short of the mark. Of course having Te in a position where it can be used readily without exhaustion is always an attractive option. As for INTPs - Their entire world is well-crafted, detached logic which seems to grant them an alternate path to understanding and dare I say contentment which I do not think my type (or maybe F's in general) would be able to achieve. There is nothing more irksome when you feel the limits to your logical facilities in your mind and they fall short of the point you want to aim for over and over. To be able to grasp in entirety that theory which always manages to somehow slip through your fingers.
