I like both but I prefer Ever After High mostly because of the fact that EAH has a main plot and I find the whole concept about wanting to rewrite your destiny to be very interesting.I also prefer the characters,animation and outfits.

Better characters in Ever After. (For example: If you watch an Ever After High episode, keep an eye on Raven Queen. Watch how when she explains how she wants to write her own destiny, the episode gets more interesting.) The plots are more interesting, too (such as in the Spring Unsprung special.).
