It's a matter of personal preference.
To me the "White Album" contains some better songs - some of my favourite Beatles tracks. But, as an "album"; as one "thing", I'd say Abbey Road. The "White Album" would have made a great single album but, to me, there are too many tracks that shouldn't have been on there - too much stuff that sounds like "filler". It doesn't sound like an album by "a band" and a lot of it wasn't, it was solo stuff. I think "Blackbird" and "I Will" are great tracks but "The Beatles"? Not really, and do they belong on the same album as "Revolution Number 9"?
