I can give you comment on the AH300 SMC GP7, seeing as it's pretty much the same front end as my current AH150-7.
My favourite Trace head of all time has to be the GP11 AH250, and the front end of this really seems to nail that sound.
What I would add is that the compressor adds more than I would have thought possible in terms of the overall tightness and sheer audibility of the sound, if that makes any sense.
Not sure I'd be overly keen on the other options provided by the GP7SM250.
I know, this doesn't help, but there you go.
