In that case, my favourite so far is River. Honestly what I like the most about it is that the creator seems like a nice guy, and I liked the talks he gave about the process of making a wayland compositor.

Otherwise, there wasn’t much difference between River and something like Sway. Sway had more documentation, and I could also use i3 documentation when needed. But I felt like sticking through figuring out River’s config file, and then it was just like any other compositor. And I liked it.
