When I think of PiL, the term "avant-garde" comes to mind. I'm not sure how well they'd fit into that, seeing as how "avant-garde" is usually used to describe scenes, not individual artists or works. They're definitely experimental, though, and make some of the most refreshing music I've heard in a while.
That said, being a person who likes the ethos of old-school punk and its rawness, I also like the Sex Pistols, but only when they were still musicians.
Also, @ rollagasper: nice avvie!
