Which is better? Huh?

Modern Warfare 2 by far....Cant compare Treyarch with Infinity Ward.

Black Ops is much better than Modern Warfare 2. However, if you were comparing Modern Warfare and Black Ops, Modern Warfare would win.

XBox Live Multiplayer is a lot of fun on BO, so that has my vote, but MW2 has a better campaign mode. Hard to choose between the two, but I've loved MW2 for longer, so I'll go with that. :D

They are both amazing in their own ways.

For one, The Black Ops campaign is by far wayyy better.

2) I enjoy the zombies feature

3)Black Ops weapons/perks/etc are better in my opinion, Ballistic and Tomohawk FTW

And MW2 I would say is better for it's maps...

Black ops is better, only cause it's newer i like the new killstreak awards in BO!  THink the maps are pretty fun also!

man thats a hard one really i loved madern warfere 2 but black opps still seems alittle better though just because of the stuff they added

hmm i kinda like in modern warfare to more that hkill streaks thoughhow u can get way higher killo streaks easier  though

COD: BLack Ops all the way...I'm addicted and zombies are badass.

Like Ramona said though XBox Live is probably why I like that one better. haha

Black Ops because better maps just a shame it has bad connection alot of the time.

MW2 was great but after playing BO and going back to MW2 its not as good as it was, another thing its all hacked now days.

Campaigns on both of them are good.  Shame the multiplayer sucks so hard on the PC. 

Battlefield 2 - Bad Company (and Vietnam) on the PC all the way for multiplayer.

All I get with Black Ops is lag is disconnections...

BO gotta love them zombies

2) I enjoy the zombies feature

WHOA...wait...there's a zombie feature?! I soooo want to play it now.

Haha yeah there is like 3 or 4 different zombie levels too. Way harder then the older version.

Black ops is way better

Black ops

I don't think this games should be compared since they are from the same maker Call Of Duty verses Call Of Duty? Really maybe a different choice of games though both games are great to play.

they're not made by the same company,
MW2 was made by infinity ward and BO was made by treyarch,
they only are the same franchise :/

Well, after staying at a friends and playing BO non-stop all week, I would have to say BO. Something like 2000 kills in four days and almost prestiging twice? ;D Besides, MW2 is full of hackers nowadays and their servers are laggy as fuck.

Black Ops, just because it has zombies

My husband plays these games all the time, and he says Black Ops because of all the cheaters that you have on MW2. And Cav maybe its your connection cause he hardly has lag or disconnect issues.
