I really like this compressor. I don't think its sound is comparable to a vari-mu compressor but it's really good. I have logic and the built in compressor offers me a large variety of typology but one like this one is missing. I use it on single instruments with a high compression rate. in this way it gives me a rich sound with tons of harmonics and a nice warmth. Great on snares, long kicks and bass. Also very handy with lead synths with high resonance. Vocals? No, not for me. If you want a free levelling amplifier the adhd leveling tool is what you're looking for.
The only thing I don't like about it is the two screws to control release and threshold. I get it, you want the look but manage that screws it's a pain. I'm not totally against the look, I like to have a good looking pluging (but if it sounds good can be just boring controls and I'm happy). please AO leave the screws and put two knobs on the right, thank you.
