Houston, we have a problem!
which group?
AniDB shows these:
- Shinji: Video: 1280x720 16:9 VFR H264/AVC (~2290 kBit/s) [ep1 and 2 is VFR, others are normal 23.976 fps], Audio: jap 2.0 Stereo AAC (189 kBit/s), Subs: eng soft styled subs (ASS/SSA)
- Frostii: Video: 1280x720 16:9 23.976 fps H264/AVC (~1533 - 1901 kBit/s [this skips pretty much from 1500 to 1900kBit/s]) Audio: jap 2.0 Stereo AAC (189 kBit/s), Subs: eng soft styled subs (ASS/SSA)
So according (
maybe wrong spelled it 
) to Anidb Shinji is better on video, but are they/him/her/it kinda "wtf is that group?!? Never heard!!!".
there is written in Anidb this quote:
"Proper" encodes of other groups releases.
Frostii is pretty known group, so then if not Shinji, then Frostii!

Currently dont have any sample screenshots to show, but already started to download em so can you give me a little time?
edit: ok got some sample images now: (left Shinji, right Frostii)
UPDATE:
Frostii seems to have dropped the series.
