AW's maps were mostly fuckin' trash, aside from Detroit and MAYBE Biolab
AW in general was actually pretty trash. Shit balancing, shit netcode, shit killstreaks.
Meanwhile, Black Ops 3 easily has some of the best content in the series. So far I like every map except Hunted, the guns are all viable (except maybe some shotguns), and the netcode is pretty damn tight.
For reference, I've played over 200 hours of AW's multiplayer and averaged a 1.3 K/D. This game so far I've put about 10 hours and I have a 1.2 K/D (but it's steadily rising), and I'm loving it just as much if not more than BO2.
