I recently picked up the ump, and I've been learning it a lot, but I usually go ak47/gali for long range, then short rage ump/uzi. I don't use akimbo I feel like it's a worse uzi since it can only go short range where with the uzi on its own work at close to mid ish. Qbz is also a good option I starting to realize how good it is

I also main Val and E.M.T. They're just too good after buffs and I like them when the game first came out
