Rock riff or Electronic riff, which do you climax on more?

Just listening to Seven Ways by Paul Van Dyke and there's these cool riffs. That's the kind of stuff I get off on.
I like good rock guitar riffs too! Like that one song by Tool, don't know the name off hand, I've been listening to that riff in my sleep.
Probably fire that song up after I finish ripping albums to thumb drive.
