I mirrored this some time ago, hoping that the original (https://www.xwinman.org) never went away.
Alas, it has.
Matt Chapman created xwinman.org at just the right time, to allow for a good selection of DEs and WMs to be documented -- with screenshots -- and where applicable -- configuration files as well.
I know that for many, it was a really good resource to discover what was out there and for people to reuse components from config files to customise their own environment.
Good luck trying to do this on Wayland...
It's a snapshot in time when things were simpler and the choice for the user was at its peak. Again... Wayland will never offer this degree of flexibility because XServer needed you to handle window management.
Nowadays, Giles Orr provides a more up-to-date list of WMs which you can see here:

Although some of curation is arguably opinionated.
But I wanted to raise the fact that xwinman.org is mirrored, and that it's a very interesting resource.
As it happens, one of Matt Chapman's programs, xtt, is something I've included #x11cp:
