I really wanted to like it but the UI always put me off. Also tending to prefer a more open development model these days. Thankfully at least for dev gitea and forgejo have both come a long way and the CI is pretty decent now (though they still dont have a gui workflow builder!).
OneDev is not fully open (there are some module for paid user), but Robin is truly available, even if the only and main developer, on every ticket you open or feature you request.
