This is crazy, but I guess it goes to show how far anime fandom has changed. For a long time if you even hinted at preferring ADV over AnimEigo you'd be shot down. Personally I think ADV is crap, and don't do the same quality other companies do.
AnimEigo at one time was the real 'fan's choice,' but it seems like they're on the way out. They've always tended to do more fan-favorites than big sellers (which the exception of the early 90's - BGC, OH MyGoddess, etc.) and as a result they have less money to buy more series. Compare this to ADV who made their initial money selling H-videos and then going up and buying all the biggest releases.
