For this kind of thing i usually go by popularity (active repo/popular repo), mostly to have the most other people in your boat. It doesn’t always work but generally if other users have to migrate at least you can ask them questions.

On the face of it i’d go with the csi driver version, only because we use alternative csi drivers ourselves, and haven’t seen any issues (ours are pretty aws vanella though).

We use storage classes (for our drivers) the “dynamic provisioning” section of juicefs.com/docs/csi/guide/pv, you’ll need to make one of those, then create a statefulset and mount the pv in there.

I do find statefulsets to be a bit of a not as well supported part of kubernetes, but generally they work well enough.
