Although BTW is the least palatable, it is the most sonically complex and interesting. Deal.

Teenage Dream>>>>Perfection>>>LOUD>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Born This Way

Born This Way

Even Adele disagrees. An album with 6 top 3 hits and a dance number one as well as a guaranteed smash has filler? And the other tracks are CTD, Who Am I Living For?, Pearl, and Not Like the Movies.
For me, I just don't like the sound of BTW, and I feel Loud is behind in quality.
TD > BTW = LOUD

Born This Way > Loud > Teenage Dream

Born This Way was the best, followed very closely by Teenage Dream, then closely once more by Loud. But they're all great albums.
