As for Battlefield, I don't know if this will be fixed on the final version either, but I recall the 360 beta having the same sensibility both for aiming down the sights and for aiming from the hip. That's an indication that Battlefield 4 is a PC-centric game and that DICE doesn't focus as much on making sure that the controls are well adjusted for console gaming, whereas the COD teams always excel on this. The animations of Battlefield are also slower, it takes more time for the character to perform certain actions, there are miss inputs too, which is unheard of on any COD. Some of these aspects are necessarily better or worse, but it gives COD the distinctive fast-paced, fluid action that a lot of people love about it. It just goes to show that it never was "just" about the 60fps; so, the fact that now the competition has that framerate too doesn't really mean much for COD. COD still has its distinctive style, and none of the other big players are really following it.
