Infinity Ward or Treyarch?

That's hard to choose from, I choose infinity ward over trey arch 60/40 only because COD2 and COD4 were the best games of the franchise MW2 was pretty good too, but trey arch invented zombies and also created COD: WAW which was based on the attack on Pearl Harbor and black ops 2 was a great game too they also introduced tanks in COD3 and in WAW but nobody really liked that idea to much. Infinity ward is winning the franchise I think because out of all 11 games made COD2 was better than the first COD by trey arch so infinity ward won the first battle, then COD 3 wasn't that good even with the tanks and gigantic maps at the time and infinity ward introduced COD4 the first modern warfare which brought a lot of hype to COD so infinity ward won that battle also, then zombies first appearance in WAW brought a lot of hype towards COD and the whole WW2 Pearl Harbor thing since some people still preferred the old wars and guns over the modern warfare stuff but then infinity ward came out with a lot of new killstreaks and guns instead of the basic three in MW2 which had the upper hand over WAW so infinity ward won the first three battles between the first six games created, then came out black ops which wasn't to great in my opinion, then MW3 was suppose to change COD in a whole new way with sledgehammer which they kept from activision all the way till the couple of months before release but Activision found out and they wouldn't let that happen they were trying to protect the usual COD gameplay and wasn't going to let MW3 be released unless they took out of bunch of things which is why mw3 was so similar compared to mw2 they also went to court for it nobody was a winner there, black ops 2 is much better than ghosts, ghosts spawns and new perks ruined the game so trey arch won that, advanced warfare is a failure which is why they are developing black ops 3, not sure what's in store for infinity ward but it seems like both developers are running out of ideas. Infinity ward had more successful ideas that brought a lot more hype, only thing successful about trey arch is zombies.

Probably Treyarch, I liked World at War and the Black Ops franchise. Infinity Ward made Call of Duty Ghosts, the worst Call of Duty I have ever played.

Treyarch, if you look at their body of work outside of Call of Duty it's a lot more solid.

Both are garbage.
