I go Picard.
Picard was just the better man... more proffesional. Less "seat of the pants" yet always knew when the Prime Directive had to be broken or they needed an alternate way to work around things... and he was a lot smarter.
Edit: The non manwhore thing is a good point too... Kirk is lucky he didn't die of space syphllius or start a war against the federation for sleeping with the daughter of some Alien Race emperor's daughter.
Also Picard had to deal with Q.
