On a more musical note, I've always rated "Let It Be" with "Coda" by Zeppelin, both albums were assembled from bits and bobs from previous recording sessions and neither one among the greatest efforts by both legendary bands.
I like Let It Be, it's a decent record and better than Coda for my money, but The Wall easily trumps both without breaking much of a sweat.
An interesting poll would be:
Coda vs
Let It Be vs
The Final Cut (Pretty much a Waters solo album and led to the dissolution of PF MK II.)
But I don't do many polls as a rule.
