Ubuntu 20.04 LTS
I wonder how stable it is these days. When it just rolled out, I installed that and it was buggy. Apparently, I wasn't the only one. Many complained about 20.4 ,dislike, even hated it like I do. After a few months constantly dealing with bugs, I decided to revert to 18.04. bionic beaver. All I can say is good luck to you and I hope you won't meet too many bugs.
One of the bugs I encountered 7 months ago was also still unresolved and I ended up having to flush the system and downgrade it.
