I actually didn't think on making a topic. .-.
Anyway, my favourite classes are Medic, Sniper, and either Scout or Soldier... or spy.
Weapon setup for each class (that have different weapons)
Scout - Scattergun, Pistol, and Bat (Don't really like the FaN, and Bonk drink is kinda useless. =w= Sometimes I use the sandman.)
Soldier - The regular, no updates available.
Pyro - Flamethrower, Shotgun, Axetinguisher
Demo- The norm
Heavy - Minigun, Sanvich, and KBG (Unless in ZF, then normal fists)
Engineer- The norm
Medic- Blutsauger, Medigun (if I'm healing a heavy or pyro, sometimes demo. But usually a kritz for demo and soldy.), and Ubersaw
Sniper- Huntsman for an open area without a lot of cover, Sniper rifle for long distance. I switch between the razorback, jarate, and the SMG. Kukri stays.
Spy - Ambassador (usually), Sapper, Knife, and generally cloak and dagger. Sometimes dead ringer.
The class I play best at is prollly Medic, followed by Engineer, probably. 8D
