I once attempted to assemble such a list myself, but quickly realized the only
objective measure was the feature set, and that's not an adequate basis for any "best of" ranking.
Ease-of-use trumps everything else by a wide margin. That's why LA2A and 1176 clones are so popular: they don't require any study or experimentation or instructional videos.
However, versatility also has to be considered. A two-knob opto can be perfectly adequate for many jobs, but not for anything surgical.
Thirdly, cost is a factor. Something like Tokyo Dawn's Kotelnikov will always rate highly (why isn't it on that list?), despite being a little obtuse and feature-light, because it's free.
Last on my list of priorities is its "sound". If a compressor sounds bad, it's either broken or you're using it wrong. Claims that a compressor "sounds musical" or that it has "mojo" are nonsense. Some are easier to dial in than others, that's all.
So how does one rank, say, DMG Compassion? If you're just counting features, it deserves to be very high on the list for its versatility. But it's fairly expensive, and its complicated UI will keep many users from exploiting all of its capabilities.
I have other issues with that list, too. Why would one 1176 clone be better than another? Don't tell me it's because of more accurate modeling, because no two
real 1176s sound exactly alike. And where are all the full-featured compressors? Is H-Comp really a better investment than something with adjustable knee, RMS detection, sidechain filters, intelligent release, oversampling, M/S, limiting and negative ratios?
The list should be titled "10 Good Compressors".
