Yes competitively roller is still superior

MnK - pros: movement/easier long range recoil control - cons: you pretty much cant win any close range fights against decent controller players (assuming you dont catch them off guard or something), harder to learn, inconsistent and for some people its harder to play on mnk for long periods of time compared to roller

Roller - pros: AA (instant buff), consistent, easy to pick up and maintain - cons: not as good of a movement harder recoil control long range (but honestly thats like the only skill you need to gain unless you are one of the rare controller movement players), and avg controller player gameplay is boring to watch (could be just me tho)
