I Would Pick Tayjutsu Its Much Faster..

[Gyro]

Dojutsu, because you can do so much with them. You can use them while using other styles at the same time. If I had to pick, I'd take the Byakugan. =]

[Wizardmaster]

Probably some ninjutsu... it would be as useful as WIZARDRY in this dimension... and long-range

[ayane]

I prefer genjutsu. I just love it! You can do whatever you want to the...victim... hehehe. And I just loove that Kurenai-Tree technique that she used on Itachi

[lasko]

Genjutsu and the same reasons as Mastaz. being able to trap others in their head and do permanent mental damage

[Naruto Sama]

Genjutsu is cool but easy to counter, unless you're up against the sharingan, Itachi countered the Genjutsu from kurenai as if it was nothing lol ^^, I would choose dojutsu mixed with ninjutsu, mangekyou sharingan + element jutsu's ownage combo :P

[Lokisama]

Obviously Doujutsu, as we've already seen what the Sharingan can do. Doujutsu is the best choice in my opinion. Seeing as the Sharingan can see through a Genjutsu and I assume the Byakugan could do the same seeing as they can see the tenketsu points of their opponent. Enough said, word.
