I like all 3, but they aren't even remotely similar.. Anyways Radiohead is much better imo. Bring on the td. Oh I'm not getting 10 points, too bad... Radioheaad>King Crimson>Pink Floyd.
I try'd to listen to them a couple of times but to me they do not sound that special :P Pink Floyd and Especially King Crimson are way better because of the innovative way they made music! They also where really influential too a whole load of other bands.
