GOUT is technically “highest resolution” but that’s not saying much. You might prefer the pre-THX laserdiscs sourced from a different master than the GOUT because it has different (some argue better) colors and less digital noise reduction (which of course also means they are grainier). As far as I know there only ever were two home video transfers, so you’ll have to pick your poison from those. I personally prefer the pre-THX master simply because it’s the one I grew up with (albeit on full screen VHS) so the colors and everything looks “right” to me.
