Depends. It’s a really easy way of bootstrapping a bitcoin node without having to do anything really. It’s very noob friendly.

I didn’t like that they moved away from focusing on Bitcoin, so it seemed at least. They’re not FOSS, so many people don’t like them for that reason. They also didn’t have any way of choosing which version of Bitcoin Core you wanted to run which is a bad thing IMO.

I haven’t run an Umbrel server in a long time so not sure what’s going on there anymore.
