Start9 Embassy gets my vote. I have that and Umbrel, and though Umbrel's UI is better, it's been incredibly buggy for me. Constantly having to troubleshoot it. If you turn it off, you might not get it to reconnect again without having to reflash and start over.

Oh yeah constant troubleshooting will get annoying over time. Is the start9 software free open source?
Yes, search this page for "open source" to learn more: https://start9.com/
Not had this issue myself with Umbrel. I've had others, but nothing that required serious troubleshooting, more of the Apple style "it's too simpled for it's own good" issues, mostly fixed by just SSHing into the Docker containers.
But yes my upcoming post will compare multiple options. Plenty available and designed to be under friendly.
Bloody typos... you got what I meant to say haha. Sleeping pattern is all screwed up atm.
