If I had to choose a VM hypervisor, I'd pick XCP-ng over Proxmox.
It’s a French product, and its interface is clear and pleasant. Essential information is well highlighted. In contrast, I find Proxmox’s interface outdated, almost Soviet-era. I know it’s performance-wise solid in terms of UX, but we can do better than this kind of Soviet-style UX.
Plus, the backup system is included by default—very practical and powerful. With Proxmox, you apparently need to install a separate OS like Proxmox Backup Server, which just adds unnecessary complexity to the architecture.
