Isn’t it mostly a case of when you entered the hobby? Like, those who were there for the earliest D&D hold Greyhawk in some kind of awe. Those who got into gaming in the late 1e/ early 2e days might have a special spot for Krynn or the Realms. A few years later, Athas, Ravenloft, and Sigil are all big. Then 3e and Ebberon.
I personally use them all. In the same campaign. They all have appeal of some kind, or can be made to with a tiny bit of effort.
I don’t think any is all that much “better” than the others, or that we need to reconcile them, whatever that means.
Maybe. I started in 2E prefer 1E GH, 3.0 F R, and War of the Lance era DL.
I prefer earlier in a settings life though. This is because there's usually something you like in it. A future author or freelancer will do something kewl which usually involves blowing something up. Often that something is whatever attracted you to the setting in the first place.
Follow on authors often think that destroying the old is a good idea to get their new stuff over. Usually fails.
