i much prefer the waves plugs, for me the overall outcome/sound is just better, and i find it easier to get what i want, perhaps due to long time use. the cakewalk plugs have a nicer gui and of course the waves gui is a bit dated, luckily that has no effect on sound/sound quality
another thing i found id that the cakewalk offerings have noticeably/significantly higher cpu usage. the first (
and last) time i loaded the cakewalk plugs in studio one 3 pro it crashed s13, the first crash i have
ever had in studio one in the 2+ years since i switched over. i'll be sticking with the waves (and other) plugs so they wont be getting much use from me.
