I had a Palworld server with Citadel since the first week of launch. It was shaky at first, but I did notice that most other Host providers had similar issues so I wont take it against them.
Since then, they have noticeably improved dramatically with better support, server performance, and also even able to display my server in the server list instead of just direct IP connection. Would highly recommend just due to how diligent they are in improving their server reliability.
