Essentially this was just a quick way for MS to get virtualization in the OS pretty fast.
This is how it breaks down:
AMD-V/VT-x: Generally slowest, but very stable, especially when the guest uses wierd processor features.
Software: Faster, not as stable. Wierd processor stuff can crash the guest.
AMD-V/VT-x + nested page tables: Faster than software, as stable as hardware. The first chips with AMD-V/VT-x didn't support NPT, but later ones.

I remember seeing a VMWare core dev speaking unofficially at a conference saying VT was actually slower and their software implementation was much faster.
