Their early minimal techno stuff isn't terribly imaginative and their pop/disco/funk stuff has always felt safe, commercial and boring to me. The only musical similarity is "use samples". I don't think they've ever ruffled someone's jimmies or done anything musically daring. They appear in Gap adverts whereas the KLF would be more likely to firebomb a Gap store.

But they are mostly safe music, never have been daring (and born to wealth to begin with, so their personal journey and connection to the world is less real and gritty). They're basically producers of polished electronic hits -- which is 1/10 of what makes KLF and their pre- and post- adventures interesting!
