I still haven't gotten to play, but the first character I'm trying out is Pharah. She looks awesome in the let's plays I've watched.
It varies, but i've been playing a lot with Soldier 76 and Moira. Side note: I'm banning every Genji main that asks for healing! Stop blaming the healer from behind walls! >.< I'm kidding, of course ; p
Junkrat mostly... Though I play Roadhog, D.Va, and Pharah also. I've played a bit of Widow and used to main Zarya.
I'm pretty into Reinhardt, although I just came back from a break and Brigette looks fun. My first impression is a duelist almost.
Its been so long since I've played. When I wanted to be mean, and a troll I would be Mei. But when it was time to get serious and we need to make a fine push I always go Tracer.
I just started playing overwatch. So far I think I like Mei and Bastion(people seem to hate him unfortunately?).
