As unlovely stated I completely agree on it that It's really depend on your gameplay Style but I would to add some more :-I think it just really depends on the situation - what you are planning to do in the game: (some of my favourite ones)
• for rushing the nexus: spy, miner, tank (ew), hero kit
• for pvping and grinding kills: hero, tank, vampire, healer, swapper kit
• for killing stacked players: pyro, pman, swapper kit
• for annoying other players: swapper, teleporter, pyro, pman, trapper kit..
I'm pretty sure that you have all kits.. so my recommendation is to switch it up time to time - just have fun and the game will seem less boring.
(btw pyro is the best kit)
