The Battlefield series always feels fresh and competitive, where I've never felt CoD has really evolved much since the first Modern Warfare game, which is why I've mostly stopped playing it. Don't get me wrong, I think it's a fun game, I just get bored of it very easily. My go-to game right now is Destiny because of it's versatility and it's dependance on teaming up with your friends to complete the hardest end-game content.
