I've been using Windows 11 LTSC for a few months with all telemetry disabled, it's a bit slower than Windows 10 but overall it is surprisingly usable. The UX changes are a disaster, however, and Explorer lags and Control Panel still exists.
Imo the usability issues are very minor. The default settings for the home edition are absolute shitshow - ads and clickbait everywhere - but those can be turned off with a few clicks.
