The version on Vimeo is much higher quality, it's a scan from the original 16mm film. Cleaner + colors are better too, the Archive.org upload has a yellow/green tint.
The version on Vimeo has vertical scratches running through most frames, which I find a bit distracting. So I prefer the Archive.org version despite it being less sharp and with the hue shift, but "diff'rent strokes" and all.
