I'd argue it's pretty hard on Windows.

NVDA hasn't worked for me since Windows 11.

Narrator + IE and Narrator + Chrome basically work but make ARIA look like vandalism. It will just be reading the text and blurt out "LANDMARK WILL ROBINSON!" in the middle of the text for no obvious reason and doesn't do it the same very time. It's basically possible to use either one of those but Narrator + Firefox is especially spastic and blurts out random landmarks and ARIA junk to the extent that it's really difficult to evaluate.

I mean, that's part of the problem, there is a spec for how HTML is supposed to be rendered, but ARIA is not specific about how ARIA markup is rendered which might means tools could bend to meet users' needs but it also means there is no such thing as "I've convinced myself that my ARIA markup is proper and will work for everyone with mainstream tools"
