The problem is their 'New Releases' are often just U.S. Renditions releases they've bought the rights to and re-released dubbed. Not only that, but the quality of their dubs leaves MUCH to be desired. In The Shell and Ninja Scroll, and the voice acting on both of those was lackluster to say the least. As for subtitles, forget it. They rarely do a subtitled version of any anime, and even when they do, good luck getting your hands on it.
Pioneer does offer a quality product and fairly consistant new releases.
As well their pricing sceme is VERY fair. Overall, a good, solid anime company. Software Sculptors gets a weird rating in the quality department. For an example, let's look at Slayers. The dub for Slayers bites.
