Land of Tears and Presence of the Dead are the two songs that I think are roughly up to par with their earlier material (lack of van Drunen not withstanding), I don't have specific riffs noted for that album but refreshing my memory, the stuff going on between the verses on Presence of the Dead is my favorite guitar-wise (e.g. 0:48/2:20/etc). I don't necessarily hate the keyboards, I think they work at times when they're being all pretty and fabulous with the leads, but I think Consuming Impulse managed to do easily as much without them. I mean, even that album has what I would call gimmicks like the faux-choir keys in the bridge of Suspended Animation, but the album's reputation doesn't ride on that because the riffs on the whole are still awesome too.
