Personally I'd hold up until the .1 release for servers, they iron out number of bugs that could impact stability. 20.04, despite being an LTS release, is quite "bleeding edge".
I always like to note that in Ubuntu upgrades to the next LTS are not offered until after it has gone through the first point release[1] (e.g., if you run 18.04LTS, you won't be told about 20.04 until 20.04.1 is out).
