prism im only positing a guess but I’d say the original is the file that all others were made from (a “Master” if you will) and from there different levels of comprehension and downsampling were added to get the file size down. I’ve never downloaded an original, so I can’t speak on the difference in quality, but I’d assume for most folk (those that don’t have a varjio or other super high res industry headset) the highest compressed file would be the economical route. Just my 2 cents though, I’m sure someone more informed will be able to give ya a better idea on it.
