I say Blops 2. Things like quick scoping require skill, and claymores and Bettie's encourage moving carefully. Halo turned into sprint shoot sprint shoot with weird magic powers and watered down kill streaks. 343 better get their act together tbh.

I mostly play campaign and mission mode type stuff, so I prefer Halo 4. IMO the Halo-style gameplay and enemies makes for much more fun in single player. Also just the style- I prefer the colorful, sci-fi setting to the more 'contemporary military' breed of shooter.
Couple of my friends really like the BlOPs 2 MP. Never been my cup of tea. *shrug*
