Rocky 8 vs 9 on home server

I recently bought a good dell workstation for cheap and wanted to set up my website and a few other things(rust discord bot, Minecraft server) on it using with proxmox so everything is separated.

I don’t really need the best and latest, so I’m curious whether I should use 8 or 9, since they will both be supported security-wise for a long time.

IMHO, if it can run 9, then run 9.

9.latest and keep up with the updates.

KDE Plasma 6 (if you can find a way to install it)
