It is interesting that you are asking people to test the “development” releases. Few years ago, this place was brimming with testers. Now, only a trickle.
I can only tell you that I have few 20.04 installs, only they are not the ‘official’ ones. Some have come a long way, from one development release to the next. I can only say that Ubuntu is doing well, even with my (franken, as few used to say) installs. Even, with this DE (3rd screeny).
Aha, you’ve forgotten Ubuntu-Kylin, which also is doing well with 20.04.
