🧠 TL;DR — Should You Use Proxmox VE?
| Scenario | Verdict |
|---|---|
| Home lab or SMB with full control | ✅ Ideal — Proxmox VE is fast, flexible, no licence cost |
| RDP server hosting with local failover | ✅ Proxmox + local ZFS mirror + backups = stable |
| You want GUI-based live backup/snapshots | ✅ Built-in with no extras required |
| You use Windows Server & Hyper-V already | 🟡 Hyper-V may integrate better with existing tooling (but less pleasant) |
| You’re in a VMware-only enterprise | ❌ Stay with ESXi if you have vCenter and DR plans |
| Want full open-source + API | ✅ Proxmox or XCP-ng both excel — Proxmox has faster dev pace |
