I don't think I've used it in ages. Maybe part of maturing as a developer, most answers I started to find there were expected and not covering the problems I faced, so usually original docs are the only reliable source, and maybe a GH issue to interact directly with the author. So I guess a tool to surface information straight from docs beats SO. Also won't complain about not having to deal with legitimate questions being closed due to "reasons".
Same for me. The issue tracker is usually the most interesting place to figure out why it's not working as expected while in the beginning of my career it was oftentimes SO.
If you're only using stackoverflow to have someone read the docs to you, then I feel you're missing the point. There is so much between the lines, and the LLM isn't 100% there yet.
