I recently did a i9 proxmox build and it became an opportunity to do a fresh install of opnsense from my pfSense install. It’s a bit different to get use to, UI wise, in some sense pfSense seemed a little more clunky but easier to read things like the firewall table. But I decided I was going to switch because of hearing the scummy things they do so this reinforced my decision and push getting use to opnsense. Good writeup
