Favorite hypervisor for home lab?

Tried VirtualBox and VMWare but then finally switched to Hyper-V on my Windows PC. The reason to use Hyper-V is an absolute flexible VLAN and NAT configuration.

Background: My LTM-VE has plenty interfaces to play with, some of them in different route domains so that for example VS-RD1 can have a pool objects pointing to VS-RD2 as pool member. I basically just need an F5 without any backend web servers to simulate everything. 

Hyper-V allows absolute transperent network access from my PC to all F5 Interfaces, between different F5 interfaces and also allows all F5 interfaces to have transparent internet access using my PC as default-gw.

Definately worth a try if you are using a Windows PC.
