This looks as uncropped as possible, with a small line of japanese text visible at the top of screen at 11:05 of S01E01.
That line of text is half-cropped in [R2JRAW] and completely hidden in [E-D] in the same scene, 10 seconds earlier at 10:50-11:00.
Probably the same for all 360p DVD-rips, although there were some 368p which I did not see.

Aside from edges though, OVAs here look good enough, but TV seasons look pretty bad, blurred and lineart jumps and twinkles (like a bad deinterlace), which is distracting.
[E-D] is better in terms of watchability. I did not see the DVD ISOs, so can't say anything about them.
