My controversial opinions:
I was a fan of Muse before I got into Radiohead. But after hearing all of Radiohead's albums, I can easily say that I prefer Radiohead's over Muse's if we were to compare them in reverse chronological order.
In Rainbows>The Resistance
Hail to the Thief>Black Holes and Revelations
Amnesiac>Absolution
Kid A>Origin of Symmetry
Ok Computer>Showbiz
The Bends> n/a
Pablo Honey> n/a
I would also like to add that Amnesiac might be my favorite Radiohead album. Which is surprising, because it was originally my least favorite when I first listened to it. This album seems to have some strange time released factors going for it.(which seems to be the case with most Radiohead albums, they just seem to get better with repeated listens)
In fact, I'll even go as far and say that the the following Amnesiac B-sides are better than anything on The Resistance:
The Amazing Sounds of Orgy -
Worrywort -
Trans-Atlantic Drawl -
Cuttooth -
Kinetic -
Fog -
