Okay, so, I want to clarify what a simuldub is, because a show getting released with a dub on the same day it aired in Japan, or even a few days after, is extremely rare (only show that comes to mind is Space Dandy). A "simuldub" usually has three or four weeks of delay because of how the production process of anime works where license holders may only get the show from the studio a week before it airs (hell, there have been a couple of shows where the license holder only got the show the day it was going to air on Japanese TV), which leaves limited time to dub the series.
