I think for many of us here mate it’s simply be the OOT. With some here maybe having a few alterations from the later SE cuts.
IIRC, a number of Fan Edits for the Original Trilogy did just this a few years back - mainly being based on the OOT - with the editor’s preference for a few scenes inserted into to them.
You also bring up quite an interesting point - which audio dubs were better / improved for the various language releases?
Good to see the 2011 audio get some love (for the sound quality from the German voices being a great improvement on the previous releases).
