Command - Tie between Imperial class Star Destroyer and a Mediator class Star Defender. In a galaxy-scale battle I’d want one of the bigger ones, but these two are just right for personal conquests.
Pilot: A-wing. But I’d want a lot of space around me until I got the hang of it.
Pilot: Tie-Interceptor (or maybe a Starfury from B-5). Z-95’s are kinda fun, too. Basically anything lightly shielded, overgunned and highly maneuverable.
Command: Miranda class (“KHAAAAAAN!!!”). Or maybe a Nebulon-B frigate.
The Aluminum Falcon? 
See, this is what television has done to our culture. No one has yet mentioned the Long Shot, the Lying Bastard, Gay Deceiver, the “Slapstick” Libby-enhanced New Frontiers, the Xeelee nightfighter-augmented Great Northern, or even the G.S.S. Suicidal Insanity.
The U.S.S. Enterprise? Are you kidding? That ship is nearly as prone to accident, incapacitation, and sudden total gratuitous existance failure as the Starship Titanic. I’d much rather fly the NSEA *Protector*, which is capable of standing up to a hideous amount of punishment even in the hands of a totally incompetent crew. And while Liberator is nearly indestructible, it seems to be a very cursed ship which also lacks even a basic operator’s manual. I’ll fly the Mary Celeste to the Moon before I set foot on Liberator.
Not me. I’ll take the Bistromath, which uses a wonderful new method of crossing vast interstellar distances without all that dangerous mucking about with Improbability Factors. I don’t want to be responsible for bringing into existance a sperm whale and a bowl of petunias several miles above the surface of a planet, only to be dashed into protoplasm on the ground below, and you just never know what other terrible problems the Improbability Drive will wreck upon your lifestyle.

The Pillar of Autumn
The OP asked about starships from movies, but some of these are from novels. Otherwise, I’d agree on the Gay Deceiver. If you’re willing to consider Star Trek televsion shows, I’d say the Defiant.
Oh, if you’re opening it up to starships from books, give me either the Dauntless or the Skylark of Valeron.*
I was going to say “Gay Deceiver,” but I don’t think it is quite a starship. More like a big car.
If it *has *to be movies, then the Serenity, definitely. Either command or pilot.
Pity, I think the GSV Sleeper Service would be cool - not that you “pilot” or “command” such a ship, but to ride in, hell yeah.
The USS Enterprise… NCC1701 No bloody A…B…C… or D
That vessel had its quirks but it never got a scratch until its upgrade.
It even withstood several attacks from Nomad with the equivilant power of 90 photon torpedoes.
It can get from one Quadrent of the Galaxy to another in meere hours…
Fast… Oh Yeah.
I would have expected the Borg Cube from such a bunch of squares 
If books are allowed, give me Dahak and we’ll call it good.
For general exploring the universe in an almost realistic movie ship - Black Hole’s Cygnus.
Nobody mentioned Planet Express Ship yet? Well, I’ll do. Either pilot or command, but preferably the latter.
Dangit, I meant to include in my previous post - Kimbell Kinnison’s Super-Dreadnought Dauntless, since someone allowed books. Naturally I’d want a Lens to go along with it.
Not to mention that it has an SEP field. So often, I’ve tried to perfect my design for a small SEP generator for my work cube, but it doesn’t seem to work quite right. 
The USS Relativity.
–FCOD
The Executor…If you’re gonna be bad,be bad well lol
I’ll take the battleship INSS Lenin from The Mote In God’s Eye.
For movie ships, perhaps the Rodger Young from Starship Troopers, or a B-Wing.
Command: Death Star
Pilot: Slave 1
