I just started playing tf2 after a long hiatus(mostly because i didn't have the free HDD space), and i must say i'm really enjoying it.
My fav gametype is koth, simple and fun, and i rarely play payload or other gametypes.
My favourite class is the Engineer, but after getting pwned by the spy a few times i usually switch to pyro and and nooburner, or scout and run around mostly hitting people with my level 42 fish =)
I also like the spy, but i have to be in the mood for it, and playing medic is always a fun/nice way to change things up.
I'll play demoman just to use the big claymore sword for fun, but i don't really care for his other weapons.
I like the other classes but i'm horrible at them, so i'll just play them occasionally, or if a certain situation warrants a certain class.
So, how do you TF2?
