The biggest problem I have with BG is the inconsistency of one particular record, I think this is mainly due to the choice of master medium between the songs and it got worse from Privateering on. SL and ATRR were mixed at BG and sound absolutely brilliant, but every record recorded there has songs of both outstanding sound quality and songs that are absolutely crap. Redbud and CBC sound very dull but the Seattle sound is superb, Pale Imitation has the best Strat sound ever (listen to the FLAC on high quality speakers, it is truly amazing, it has so much depth) but Don't Suck Me In is missing a lot of punch. Pre-BG the records were very consistent in sound, MM has a particular sound, BIA too (like it or not), STP has it's own sound, etc...
From the DS record I like BIA and OES the least, LOG has far too much reverb but I can life with that. The first and second record defined the DS sound and are therefore classics. Jimmy Iovine did a wonderful job on MM, the drums are just fantastic, what a powerful record!
STP really defines the ultimate MK sound for me, great Strat and Les Paul sounds, rocky drums, just the right amount of reverb and I am sucker for Guy's sounds on that record. RPD and SL too empty for my taste (and the music waaaay too slow on SL, great lyrics though), ATRR very close to STP. From the BG-area my favorite sounding record is Get Lucky.
