They have a really big artist alley. I went through there last year and since it's a smaller con, I noticed some of the bigger names have AA booths that you'd never find in a booth at SDCC b/c it's too crazy (Example, Kelly Sue and Rob Liefeld had a booths in AA). I'm not sure when they get around to announcing who all is in AA though.
Also, last year DC had a big booth and signings all day long with the bigs. I like their DC Events App, it shows all the signings and times and you can set alarms on your phone. Show an hour early to line up though, they don't let the line grow very big before capping it.
