I have:
1.) Original Geffen USA pressing "masterdisk" etched in dead wax of Nevermind, bought day after release
1a.) "320" EU pressing of "Nevermind"
1b.) ORG of "Nevermind"
Of these three (and all are good in their own way), I would have to give the slight nod to the ORG in terms of overall detail and clarity of bass HOWEVER...the original USA pressing has that magic of how it was supposed to sound, raw. The EU is also very good, I'm glad I have all three.
I had, and soon sold, the MoFi. Just awful, muddy. They go for way too much money.
2.) Original Dutch pressing of "In Utero"
2b.) ORG of "In Utero"
LOVE the ORG here. Great bass slam.
3.) USA black vinyl pressing of "Unplugged"
3b.) ORG of "Unplugged"
Both are winners, hard to distinguish as the recording is superb.
