This could open up a hornet's nest...the "best?" I like the mono reissues if you can find them. I also like the stereo box of the white album with the Esher demos, which is probably cheaper than a mono copy. If you want "very good" then the stereo represses are solid and much more affordable than the monos. Beatles purists may disagree but I think you'd be happy with the clean recent stereo represses.
