either one will give you about the same power really. The comptech I like a lot more not only because of its looks, but it also makes (from the tests I've seen - independant) a little more torque than the AEM and in general has a better power curve. Now a lot of people will scream AEM, but Comptech's icebox is hard to beat. It's also pretty safe and streetable, and it uses a foam filter which actually (theorteically) flows better than the K&N gauze. However, it also does not filter as well.

My vote is with the comptech, and besides, you'll be a little more original than everyone else with that.
