I had issues with Manjaro and WiFi disconnecting. Also, Manjaro dropped hardware acceleration for video codecs. Eventually got too annoyed to deal with the Manjaro direction and moved to EOS. Everything is working fine barring a script to get the headphones volume to work (recognised as bass speaker in alsa paths). So far, EOS has been the set and forget type of OS for me.
Didn’t bother going through the hoops and installed EndeavourOS which is arch-based with some additional default applications.
For me, the best thing of Arch isn’t the distribution but the Arch wiki. An impressive piece of documentation.
