Depends on the class and the given situation. But the ones I stick to most are:
I play mostly old-school loadouts, with minor variations or reskins.
If I had to pick one of those nine, it would probably be the Snipers.
Engineer, Spy, and Scout are my favorite classes, but I pretty much never change that Sniper loadout. It works for just about every situation.
