I remember on here an expert called 'Mr Stinky Pants' or someone?
Also known as The God Thing
. A fellow fan from Sydney who moved to the USA. We passed in similar circles in the 80s, did the same weekly comic runs, remember the same bookshops, saw the same sneak previews, but never met.
I would assume it is whichever version people owned on VHS/Beta/Laserdisc back in the day and rewatched a lot!
A true completist has each copy. I still own TMP theatrical in Beta, VHS scan & pan and
VHS widescreen, plus the Special Longer Version on VHS, the DVD DE, and
an iTunes download and Blu-Ray of the theatrical.
