the gimmick ones like the Moroder are interesting as their own things, but yeah there's no reason to go with anything other than the modern restored to see it for the first time
over the years it was a hell of a thing to see the fugly pd print of the 90s to the Kino restoration from 00 with the "there was a big plot about Hel here, but we have a photo. you're welcome" to the print that belonged to nobody in particular that surfaced in South America
also the novel is worth checking out, iirc it's sorta like 2001 where Thea Von Harbow wrote it more concurrent to the movie's development more than MOVIE THE BOOK or BOOK THE MOVIE but it's a nice take on the story, and for a long time was IT for finding out about Yoshiwara and that guy
