Using 20.04 is certainly supported for some years yet (https://wiki.ubuntu.com/Releases) but:
* Some people don't notice the difference in the version numbers and accidentally install the older version; and * Plenty of bugs get fixed without official tracking so trying the most recent long term release is certainly recommended.
I think you will enjoy 22.04 more too.
