RDP is really quite impressive. I host Windows VMs on a Linux server. With quickemu[0] you can fire up a Windows Vm in minutes. It fetches the ISO, sets everything up - even breezes through setup, creates a user, does KMS for activation, etc. One command and a few minutes later you're looking at a Windows desktop. Setup Remote Desktop (with SSH forwarding or VPN of course) and you have a remarkably responsive (even at 4k single and dual display) GUI experience and powerful remote connection - file sharing, sound forwarding, clipboard sharing, even printers and arbitrary devices.

I think you misread my comment.

If you're using a Windows app as part of your Mac workflow (which is often the case if Fusion is being used), you'll put files in a shared mount so the Mac and Windows apps have access to the storage they're on. This doesn't work if you have to transfer files across the internet to start the Windows side of your workflow.

For example, a Windows reporting tool that reads from an sqlite database, which was generated with a Mac workflow, while I'm sitting at a coffee shop.

And, the nicest thing about fusion is that each Windows app appears as a native window, which RDP doesn't seem to have.
