I have tried all of them and yunohost is the best for me. I have been able to test self-hosted software that I could not otherwise. Cosmos and CasaOS work for many people, but they did not use some of the software I wanted to try; when I tried to set up a docker image of those pieces of software, it did not work. I understand that it was my failure to understand docker that failed here, so if you know docker, these might be much more useful to you.
