I can't rely on CN to quench my thirst for anime. Anything aired prime time, or even mid-day, is usually aimed toward a younger audience. The licensed shows aired on adult swim are of much higher quality, because the show isn't rescripted, edited, and butchered from its original and wholesome form to appeal to children.
I believe you won't find the absolute best anime on American television.
Go online, and find quality fansubs.
A few US licensed ones are decent, but nothing can beat the original. :|
