I’m running River on Void Linux and must admit that I’m really happy with its user experience. The development is quite transparent and the founder/main developer is well known in the Zig community, there’s also a talk about creating River by him.

As far as I know, Weston is not really meant for being used on a normal desktop (not really sure anymore).

Wayfire is awesome if you like animations, but it wouldn’t be my case personally.

Can’t say much about the others unfortunately.

No worries, I’m used to that from other projects I’m working on :)
