it is all personal opinion to who is " Better "

I like Tool better becuase they have a Harder side that APC.

now if you are talking about skill in music Tool is far better, Tool is like the Mozart of rock, and APC is more like the Bathoven. Dany Carrie the drumer for Tool is insanly good one of the best in the world, and the guitarest makes the best sounding music even though it is realitively easy to play. APC has the guitarist is from "The Smashing Pumkins" he is damn good as well.

seen them both live they both kick ass but IMO Tool is the winner becuase they rock harder.
