Indeed, if you prefer long term stability then you should stay on 20.04.

We will be backporting some performance fixes to 20.04 as soon as it is safe to do so. In fact a couple are coming in mutter 3.36.4 and another in 3.36.5...

If you want to make 4K significantly faster on 20.04 in a safe way right now, then I recommend forcing it to use the old Intel driver which is better at frequency scaling. Just edit /etc/environment and add a new line:

  MESA_LOADER_DRIVER_OVERRIDE=i965

and then reboot.
