The USS Bellephoron! (Intrepid Class). A ship with no real reputation (I'd give it one). Intrepid class ships are small enough to get to know your crew and bond well as a unit but large enough to kick ass and be comfortable at the same time (no Defiant crampness - can't stand that
). Second choice would be the Ent-D because it is massive and, again, I'd like to be able to chillax a bit and the ship is certainly large enough for that
Plus you get to feel important being in command of the largest ship in the fleet.
