I work to get the mix to sound GREAT on it's own, then it's done. No need for 2bus comping; it can and has been done thousands of times. I do not mix things for radio, and 99% of people who do never get there. Radio is NOT a good sound, is it? Why do it? Go for a GREAT sound - huge and powerful, dynamic and controlled. In your mix. Even in mastering, we barely use compression, maybe a top limiter.
This seems to be a "thought process" that is common to people who compress and EQ "to tape" too. They want that finished sound N O W ! ! ! Just different schools of thought, eh? I will print EQ or slap to tape if I need it, but I generally will not re-do that effect, just use it "as is" when mixing.
One of my "rules to good sound" is to never do the same thing TWICE, if you can. Putting audio through things is what kills sound. Don't compress the bass to tape; you might want more (or less) when you mix. Don't EQ the snare "to tape" if you are going to EQ it again. Don't compress or Finalize the stereo bus; it will be done again in mastering, with better QUALITY gear than you probably own, when it is SAFE to judge the levels and tones needed for the overall album.
