Of course it’s more important. The best official release is (arguably) the GOUT. In spite of twenty years of fruitless rumors to the contrary, this is unlikely to change within our lifetimes.
Unless you have terminal cancer and are going to be dead within the next year or two, I’d take that bet.
And BTW I think the Japanese laserdiscs from the 80s look better than the GOUT. They’re noisier, but the colors are better and the detail wasn’t scrubbed out, nor are there any motion smearing artifacts. Because the GOUT is digital, slightly higher resolution, and cleaner, it makes for a better source for something like Despecialized. But if I could only choose an official release of the OUT to watch, I’d go with the Japanese laserdiscs instead. Sad how literally the first ever widescreen home video release of the trilogy remains the best official release to this day.
