I use https://github.com/luantak/FokusLauncher and while I don’t think it’s all that great it hasn’t annoyed me into switching back (which is a low bar given how easy it is).

Considering all of them are supposed to integrate with each other they’re relatively hard to integrate. I find it rather astounding they haven’t figured out service discovery.

I think Incus was one I had trouble with. It did run without systemd but part of the installation I had to do manually.

AntiX Linux has been the most efficient distro on my netbook. You gotta be okay without systemd though. For the most part I didn’t need it but some things are highly dependent on systemd to work.

WattOS was good too but AFAIK it’s not actually open source so I couldn’t trust it.
