I compared 1ep A~A vs Arigatou:
Subs - same (yep, same weird engdub subs, but A~A have SRT format (only) + hardsubbed OP (only OP) (funny, you need switch off subs when watching OP, because they annoying with hardsubs))
Video - 640x480, I don't want waste my time to upload screenshots, but i found that video worse (some scenes have less details (like RaX release)) then Arigatou (+ A~A video blured too much for my opinion (Arigatou colors better)), If someone says: "You don't right, I compared video and A~A much better

" be sure do it with comparision screenshots

.
(I don't "protect"

my upload and I always replace my files with better version, but Arigatou still better.)
