8200 is still my favorite. I have a 8500 and it's louder, but still haven't been able to get it to sound as smooth as the 8200. The 8200 sounds fine without anything in front of it. May sound fine with stuff in front of it too, but I wouldn't know.
Run the bass boost in the 6p range. Boost the brilliance a bit.
Run the AGC release pretty fast (I run mine about 8db per sec). Otherwise, it swallows vocals.
Don't drive mutiband too hard 15 is plenty. The final clipper is good and clean up to about +2.0.
I shut the gate off. Even at it's lowest setting, (-44 I think) it sometimes gates going from a loud liner or somthing going into a song with a soft intro, and then people in cars can't hear it, as it slows the release times down too much.
Biggest problem I hear, is Band 1 attack time is a little slow and sometimes distorts a bit until that band starts to limit, then it cleans up.
Good Luck!
