The whole point (from a savvy business perspective) is throw money at the hardware and throw experience at the software. In the end, Proxmox is based on KVM and KVM does run a workload or two across the world. VMware isn't KVM and I watched both be born and grow up oh and I should mention Xen but I can't be arsed. Most of the rest are Johnny come latelys. If I need a massive cloud then I'll go all in on K8s or whatever and get my orchestration hat on big time but for my needs and my customer needs, PVE is more than enough, whilst being just enough.
