Skyrim's editor was super intuitive and crashed very little for me, just like the Oblivion editor...
However, they never allowed innovative mods, especially the oblivion one.
EDIT: on a different note, I hope Asset import/export is simplified for BG3, if it is going to feature modding at all. Couldn't get a single 3d thing in DOS2.
I'm curious about what you thought was lacking? Not that I'm saying it wasn't, just interested. Your "different note" suggests where you're coming from as I probably spent way more time using third-party tools to do 3D editing than I did in Construction Set; and even when it came to integrating them into the game I'd use TES4Edit as it didn't make a mess of my dependencies!
But for world-building and scripting there was no other choice.
