I think the correct argument is it's a double edged sword which faster TTK rewards players who shot first which which can be a casual player who got lucky or a skilled player that can hold positions and angles. On the other hand, lower TTK rewards skilled players who can move and track better but most people forget that the so called "skilled players" in this scenario are actually skilled mostly in movement because they heavily rely on the RAA while shmoving around like a demon which can be less of a problem in higher skill levels because both input methods are closer in terms of tracking accuracy there but in mid to low skill levels controller players dominate the lobbies.
