Speaking of Kirk, I just cannot imagine him filling out forms and whatnot. Picard seems like he would be the most okay with the administrative side of command, mostly because he can just grab a nice cup of Earl Grey, turn up the Van Halen and work in his ready room. Sisko, I imagine, had a pretty heavy workload. He had to manage a mixed crew of Starfleet and Bajoran military personnel, in addition to the civilian population and a warship. Janeway likely had it the roughest, since she probably had to deal with the upkeep of Voyager and its crew without the benefit of starbases. As for Archer, no clue.
Heh, maybe that's the real reason why Riker waited so long before accepting promotion?
