And these would be better then SS because....?
AC3 audio, DVD source as opposed to subpar* TV-raws, higher video bitrate, official translations (whatever that's worth)? Actually, it doesn't matter, as SS-Eclipse's version wouldn't have to be replaced. There are a number of other series where fansubs and sub-only R1 rips coexist, like Girl's High, Kashimashi, Emma, Dokuro-chan, etc.
*Apparently all BS-i 4:3 -> 16:9 shows have Raw issues.
So says mentar.
