Bottom: R2J Toei
The R1 isn't perfect, but I do prefer it in terms of video. I don't have the disc here right now. I remember at least some of the R1 releases had a pretty rough audio (such as the Oyama films, I think) but I don't remember how this was. Toei's audio is fine, as usual, so that could possibly turn the tables.
BCI also put this out on double feature BD with The Killing Machine. A German BD also exists.
