Anamerican kinda take the piss a bit. First they try to draw it manga style, which in most cases is really crud. Not being big headed or anything, but I could probably draw better than them. They also have the most lame battle scenes ever. They have about 3 frames for positions for each character, which is lame. Finally, the storys are usually of poor quality. Some have ace story lines, but are ruined by the horrible voice overs and terrible animation.
Back on topic, I think Shaman King would have to be my favourite Anime. It has great action, A story line that would catch my attention, and a great soundtrack =D
