yeah..for me, I bought the SSL Waves plugs and I had already bought the URS. Well, I thought for sure Id be using the Waves all the time, and I really just use the Bus compressor, and not even on the 2bus! I love what the URS plugs do more, even though popular opinion on here leans toward the Waves.
Personal opinion and experience.
Try driving those plugs and see if you like the sound. Only way to go.
