Blue Exorcist - Episodes 13 - 17 (Dub) and the two Ura-Eku's which were on disc 1.
Gotta say, as of late Viz Media and Aniplex seem to be the only ones really putting out decent dubs, with Blue Exorcist and especially Tiger & Bunny probably being the best two this year by far. From what I've heard of it, Fate/Zero is also pretty good (But it's Fate, so naturally the Japanese Dub will always be better). I'm not saying all of their stuff is strong though, just that the smaller range they output is usually better quality. Sword Art Online for example is very hit and miss, but part of that may be due to the rushed nature of the show and occasional silly over-emphasis on lines. Maybe this is a result of outsourcing to other studios, and having access to a wider cast, rather than doing everything in house and re-using the same cast for everything (FUNI, I'm looking at you here especially). I don't have a preference for Dub/Sub, but I honestly don't mind paying the price for Aniplex's releases because they always get it right, whether it's Product Presentation, Extras, Dubbing or BD Authoring.
