Wow I didn't expect the first thread I looked at in this forum to feature my favorite band Porcupine Tree! They are indeed awesome. They take rock and do something original and creative with it, instead of recycling the same old riRAB and cliches. At the same time they avoid the pretentiousness of prog and art rock. Although sometimes I enjoy some slightly pretentious prog, like Pain of Salvation. Actually PoS is a very close contender for best band ever, IMO.
