Sound quality is fantastic. I like the Giles Martin mix, a lot of others don’t. However I think the criticisms I hear, that they’ve made a stereo mix that sounds too close to the mono mix, are really unfair given that this was exactly what the goal of the whole project was.
Beyond that I think the second LP is a load of trash and not worth the wax it’s pressed on YMMV. It is on streaming services if you want to check the quality of the music on it before you buy. I got the 2LP at retail when it was new so don’t feel too bad about it but I don’t think I’d be spending big secondary market money on it now.
