I just realized, I never responded back to you. Oops! Lol, I can't say I've ever heard of either of those. May have to check them out, because I've been looking for something new to watch. Revisited SAO just for the sake of enjoying the story all over again, and before that I watched Tower of Druaga. For me, the hard part of putting together a cosplay costume would be the time. With my work schedule and social responsibilities, I doubt I'd ever finish one if I started!
