From the perspective of a HC Dom player, Vengeance over Apocalypse for me. I like all of the Vengeance multiplayer maps (Cove, Uplink and Rush are some of my favorite maps, Detour is OK) but the Apocalypse maps aren't quite as good (Dig can be frustrating at times, Takeoff and Pod are just OK, Frost is great). Zombies maps are a wash, in my opinion, because I can guarantee in like a month people will realize Origins is overrated, just like Mob of the Dead was when it was released. On a side note, might be best to either get all the DLC or none, otherwise it might be harder to find matches. Not impossible, but harder, especially if you play a more niche playlist.
