Tried bitcoin core on Linux, mynode, umbrel and ended up choosing start9 for stability, security and ease of use.

I use linux (nixos) with bitcoind running as a systemd service. if I need the gui I shut down the service and open qt.

I run core-lightning next to it as well (I was one of the first 5 nodes on lightning mainnet, and that same node is still running). I probably have the oldest running lightning node.
