Honestly it comes down to if you like the MW series or BO series. Ghosts isn't like any of them but it's closer to the MW series. You die quick and you kill quick, there's multiple weapons in all classes that work well and the killstreak system is the same as MW3 with Assault, Support and Specialist.
And let's face it, even the people who hated the game can't say they didn't love the friggin Honey Badger
The only things I don't like about this game is how easy it is to camp, successfully. Throw down an I.E.D. cover the other side with your silenced LMG with thermal scope. If you would be willing to dish out a few extra dollars pick up the Ripper. It's the only gun I've found on the game that can compete with the Honey Badger. They both do well regardless of range and the damage they dish out is also great.
You will rage a lot, but it's also a lot of fun.
