If you are trying to list plugins to ween UAD users off the crack then I applaude your efforts, though far off you are in many of your comparison/alternatives.
I have replacements for some of the plugs, the ArtsAcoustic range certainly help take the edge off the pain... There are plenty of good native plugs out there, The Glue, the Steven Slate gear etc etc... but no other algorithms that do it in the same way. 100s and 100s of person hours have gone into them, and aside from the fact that they are emulating actual hardware units - many of the plugins are the best in their field. The Moog filter for example, (until hopefully The Drop) just pwns all other filters. Don't debate, just listen to it. The EMT140 plate is stunning, and I'm not sure if I WILL find a replacement for it...
The VOG, um, good luck! ...The EP-34 has such a unique harmonic feed and temperamental nature that I can't replace IT. SO MANY of the plugs have NO real alternative, simply because of the SOUND!!!!!!!!!!!!!
I have 'A/B'ed till the cows came home.
If you are just making a list because you hate UAD or something, then you are kind of wasting your time. I'm not trying to burn, I'm just saying that this is either just too subjective, or missing the point that these plugs are emulating gear that is very unique, and has a certain SOUND...
