In my opinion, I think MW3 is better because it has better graphics than Black Ops, more "Leveling Up", and better maps.
Black ops is a lot better than MW3
I have black ops and MW3 but I find MW3 to be better but you do get bored of it as you do with black ops but I recommend MW3 but black ops is fine.
no
yes
It depends on what you are looking for , black ops has zombies but on mw3 it has special ops where you have to survive wave abit like zombies , in some ways its better than zombies . online on mw3 it has 3 different types of kill streak , you have support where if you dye it carrys , assualt where if you die you lose it , and you can get perk kill streaks . The missions for mw3 are a lot better than black ops . the emblem creater has gone but in my eyes .... Mw3 is better But battlefield 3 for the win.
It is based on what you like. Some people like MW3 over Black Ops. And some people like Black Ops over MW3. MW3 is almost exactly like MW2, so if you like mw2 then you should like mw3 also. (:
I'd suggest Black Ops.
Well, it will obviosly be better than Black Ops because MW2 is a lot better that BO and MW3 is supposed to be amazing and the most realistic game in graphics and in story. You have to do what you would do in real life, clean humvees, you have jobs and chores to do, you get in a lot of combat.
Black ops is better for kids because there is a setting in the Game to restrict the graphic content such as blood and language. On MW3 its more of a hardcore time game.
There are different games with different developers and the Call of Duty MW3 still has not outsold the Black Ops even if opening sales were better. Black Ops II will be sold starting on November 13 2012 and if presales on the new game mean anything Black Ops was liked by more than MW3
Black ops came out in Nov 2010 MW3 came out in Now 2011
MW3 is after COD black ops.
