Kirk because:
1. If Deanna Troi went on his bridge he would either sleep with her or shoot her.
2. there are no kids on Kirk's bridge *cough* wesley crusher *Cough*
3. Kirk gets laid. A lot.
4. Picard always follows the prime directive, Kirk does his own awesome thing.
5. Kirk is sexy.
6. Two words; Shoulder roll.
7. Spock> Data (I'm sorry, believe me this was a close one)
8. Kirk isnt afraid to swear, he says "You klingon bastards you killed my son!" and "Double Dumbass" (lol on the double dumbass thing, star trek 4 ftw)
9. He just is supreme in everywhere.
10. His philosophy is "Shoot first, ask questions later", Picard was all diplomatic which was no fun. Pew Pew!
James Tiberius Kirk all the way!!!
