Both are bands deserving of high praise...I'm not sure Radiohead has much left in them...but in all of Rock History, few have a stronger overall discography.
Arcade Fire, Funeral excepted, is just not in the same league as Radiohead on record...really not even close, but they are a better live act.
If we've got to single out anyone out of this bunch as overrated...it's Thom Yorke solo...the mediocre quality of his side projects/Atoms for Peace efforts signal pretty clearly for me that Radiohead's creative success is very much a full band effort...not the product of one lazy-eyed, mad creative genius as the press often makes it out to be.
