I would partially agree with this, in that I love the song Echoes and I think it is essential in the Floyd catalog. However, Animals gets my vote because I think that it is the stronger album overall. Momentary Lapse is also very good.
By the way, Echoes was amazing when Gilmour played it live this year.
