I've been on Proxmox for 6 or so months with very few issues and have found it to work well in my instance, I do appreciate seeing another alternative and learning about it too! I very specifically like Proxmox as it gives me an actual IP on my router's subnet for my machines such as Home Assistant. So instead of the 192.168.122.1 it rolls a nice 192.168.1.X/24 IP which fits my range which makes it easier for me to direct my outside traffic to it. Does this also do this? Based on your screenshots, maybe not, IDK.
