I prefer v1, but in Percona's build of PMM v1 there are several bugs /
missing features that are going to cause you problems with newer
kernels and MariaDB 10.5+.
I have patches to fix it, but my build of it is not yet publicly
available. But v2 is still far better than no PMM.

I cannot say I have looked. I'm generally happy to leave testing to
others until I have an overwhelming reason to upgrade to a version
with a lot of changes. And 10.5 was a rather big feature release.

Replication from newer version to older version is also not officially
supported. It usually works, though.
