The treyarch games are consistently good and offer more variety with their zombies modes. Advanced warfare sucked so that's a no to sledge. ghosts was pretty bad but even tho extinction mode was clearly an attempt at trying to have their own zombie-esque experience it was actually better then I thought it would be (still not zombies tho). So while modern warfare 1 and 2 were 2 of the best cods in the franchise bc of their campaigns and multiplayer modes. The developers don't always deliver a game that trumps it's own previous title. Which is why I only by treyarch made cod games. I recommend that everyone just pick their personal favorite developer and stick with them, I see a lot of people complain about cod games all being the same and how they're getting tired of it and so on. But if you wait 3 years between each cod game instead of 1 you will be much more excited for each new entry made by your developer. And by not playing the cod games developed by companies you don't like it won't taint your experience when you finally do get the cod you want.
