What Linux Version?

Been trying to find info on the web but cant find any.

Is there any major difference between the linux recommended versions?

5.8.16 and 5.4.11?
Both are recommended.

I ask because in Ubuntu, 5.4.11 is in the repositories and I have to manually install version 5.8.16.

I assume that when the repos are updated, it would update me to 5.8.16 anyhow?
