I switched to daily driving OpenBSD a month back and it's been such a smooth and great experience. by far one of the easiest OS installs I've ever had (it's essentially a yes simulator). and what I love about OpenBSD is to get everything working, wifi, gpu drivers, etc it's literally just doing fw_update in the terminal and that's it. the upgrade process is just as easy.

It's so stable, everything is fast and it all just works. plus a fantastic and supportive community backing it.
