One of their best albums for sure :)
Dogs is probably one of the best pink floyd epics, and sheep and pigs (three different ones) are just amazing, and pigs on the wing was a very relaxing addition to end the album, and I really liked the fact that it ended on a much more optimistic note.
Though the album is very political and deals with very dark themes within it, I never felt that it was pretentious or being overly cynical.
The concept of the album, which was heavily inspired (i think) by George Orwell's "animal farm", was quite interesting as well.
Most importantly though, this album experimentation with music, the musical production and the obvious avant-garde elements present in all of the longer songs, probably influenced most of the experimental & progressive rock genre for decades, which itself makes it a 10/10 for me :D
