Maple Films is the Hobbit edit I go to. It’s the only one I’ve checked out that truly feels like it works as well as it’d need to on its own. It’s not perfect, but it’s the best IMHO.
When I check out a Hobbit edit, I use the barrel scene as a litmus test. If it goes from the music obviously ramping up for an action sequence to the dwarves floating listlessly, as they almost all do, it fails the test and I look no further.
I previously stumbled on M4’s Hobbit “Book Edit,” and was drawn to it because of his goal of bringing the trilogy more closely aligned with the original book. I’ve downloaded it but haven’t watched it yet. Did you look at that one?
ETA2: I’m interested in a link for your TLJ Legendary Cut.
