A notable mention is https://ubports.com/en/ which is different from postmarketos in a sense that ubports uses old kernels with heavy patches. That means: good support for things, but difficult future.
PostmarketOS uses the newest kernels and tries to integrate their patches into mainline kernel, so that the reliability is maintained with all kernel developers.
I only use my desktop for gaming now but it’s old and won’t run Win11. I’m going for a SteamOS general release then I’ll just drop windows on there altogether
