TBH all of them work pretty well if you dial in the settings right (all have their own unique characteristics of course). But I usually use SSL channel (I prefer duende ssl over waves, but both work fine) or Waves 2550. Sometimes I'll use CLA76. Usually my attack is at about 30ms, 4:1 ratio, release (depends), actually, threshold, attack, release all depend on the source and what type of music is being mixed.
