idk how to explain this so im going to try my best
humans have an innate desire to maximize like a so-called "happiness level" if given two choices they will choose the one that makes them happier
different skins and different vfx and different sounds and some vandals feel better while tapping and some vandals feel better while spraying
not sure if this applies to all people but sometimes when i change my skins it influences my playstyle and my shooting style
like ex. if a vandal sounds cripsy while tapping, at a subcounsious level i would find myself tapping more
if a gun sounds bad while spraying like certain guns when u spray the vfx overlap and it gives a sluggish sound u would be tapping more
the kill sound is what makes or breaks the gun. take recon for example
the better the sound -> more motivated you are to kill someone because u innately want to hear the (satisfying?) sound after you kill someone
and inversely if a gun sounds like shit u would be therefore less motivated to kill someone because either the sound is annoying or whatever
same with knifes at a certain level different knives have different pullouts and inspects and that influences when u pull out ur knives and stuff but thats not important
