I honestly find a fantasy setting more interesting when the wide world isnt that overlyspecific and overlydeveloped, especially when the smaller region in which the game is set in is better developed and explored.
Greyhawk is ok because most old modules of D&D fit in It without much fanfarre and still makes sense because, well, It is always a localized dynamic.
In forgotten realmente in which every region and locations is more well defined and detailed you have to find ever more reasons to fit things. And this is How we get a ton of planes of existance and dimensions and multiverses etc
