I find it makes my life easier, personally, because I can set up and tear down environments I'm playing with easily.
As for your user & permissions concern, are you aware that docker these days can be configured to map "root" in the container to a different user?
Personally I prefer to use podman though, which doesn't have that problem to begin with

Same here. I self-host a bunch of dev tools for my personal toy projects, and I decided to migrate from Drone CI to Woodpecker CI this week. Didn't have to worry about uninstalling anything, learning what commands I need to start/stop/restart Woodpecker properly, etc. I just commented-out my Drone CI/Runner services from my docker-compose file, added the Woodpecker stuff, pointed it to my Gitea variables and ran docker compose up -d.
If my server ever crashes, I can just copy it over and start from scratch.
