Well, in the original, King Kong won. Not sure about how it's going down this time around. But in reality, Godzilla beats a giant gorilla.
Until the day he died, my dad and I aruged who won. I claimed Godzilla the victor, while my dad went with Kong. But, there are actually two versions of the original movie - the one you reference with Kong "winning" (yet swimming out to sea away from where the fight was), and the other where you hear Godzilla roar after they fall into the ocean, so the lizard "won". I believe the latter was done by a Japanese director and is typically only available in Japan.
As for the new movie, as a lifelong Godzilla fan, I already have a ticket to see it on opening day. And I recently subscribed to HBOMax for Zach Synder's Justice League, but plan to watch GvK right away again after the theater.
