@pupy@chitter.xyz I've only really had experience with hammer (the editor for hl2/portal)
and it's always super arcane.
It frustrates me that there doesn't seem to really be a middle ground between "powerful enough to allow you to build whatever you want" and "easy to learn" for level editors.
(I find this especially frustrating for hammer – the tools it gives you are amazing, but the UI is horrible)
