This a very well recorded album and IMHO it would be hard to go wrong with any VINYL LP pressing. My own GEFFEN copy is a recent EU reissue and it sounds superb.
Here's the GEFFEN EU Reissue label.
That said, one of my AUDIOPHILE buddies is a huge NIRVANA fan and he assures me beyond a shadow of a doubt, that the ORG (ORG034) pressing is the one to have - if you want the best.
The label of the ORG is quite different, as below.
