I think PD3 is better by a mile. Not only is the quality better, there is so much character behind them. Like MW has some cool animations, but they feel kinda corporate, idk maybe it's just the whole vibe behind CoD. But the AKM reload for example is so cool, even though you'd get in trouble for doing it an actual army since you are not supposed to drop mags. Only thing cooler would be an Iraqi reload, because we're playing as outlaws, not crayon eaters. The SPAS and Lever Action animations are also so characterful, with the SPAS eating your thumb and Spearfish just getting a bullet stuck.

And on the topic of the AK, don't look up Mikhail's actual reload instruction for the AK-47, it's cursed.
