I enjoy tool more, imo their enigmatic lyrics coupled with some awesome kickass music makes them more appealing to me. Vicarious made it on Rolling Stone's list of 100 best rock songs ever made, Prison Sex was such a good song that MTV had to ban the video because it was just too good, and Parabola is one of my favorite songs ever. Sure, APC has a lot going for them, but to me they just don't have that same feel like Tool does.
