I’ve used solely CasaOS for about a year. As someone brand new to self hosting with limited knowledge or desire to understand all of the details, it has been relatively straightforward to work with. I have learned about docker and how it works through using it and have a appreciated the plug and play store options when I haven’t had time to work it all out myself. I am considering moving to Yunohost because of the good things I’ve read about it, like the other comments here, but docker seems to be the best way forward and as CasaOS does that reasonably well I may also just stay with what I know.
