It seems that Start9 is more robust/pro.

I tried playing with a raspberry pi by myself, but unfortunately I don't have the time for it.

When my umbrel home arrived, it was up and running in 2 minutes. Downloaded bitcoin core and a few other apps, the day after everything was ready to be used. People report security issues with umbrel, like HTTP and lack of encryption, but I guess it's only a problem if you're a target with a lot of resources (not my case). I've spent more money with umbrel home and miners than my total bitcoin reserve 😂
