I like Standoff, Overflow and Hijacked.
My reasoning for hijacked is I can run round with a shotgun, or play defensively as with a Betty and scavenger either of the upstairs rooms are defensible. If you play with a team and try to not flip the spawns it's a good map.
I'm warming up to Hijacked...Probably the smallest map I have cared for since Rust.
Then Standoff, Slums (More on Objective modes.) Drone, Meltdown, and Yemen can be iffy, but honestly my fav currently out of those would be Standoff for some reason.
Stand off, Raid, Slums. no particular order. It depends on the type of game.
I really like slums for demolition.
Cargo is lots of fun on domination.
Hijacked is a love/hate affair.
Especially for a AR user.
