As far as I had experienced, home and professional edition differ in certain things.
For example Professional as its name says, has less wizards for creating or customizing more technical issues such as networks, firewalls, etc. Lets say that home is a bit more automatic than professional. professional lets u do more things, but its interface becomes a bit more for advanced users(complicated should we say).
It depends on how ur windows and technical level is... in my opinion comes down to it.
Hope I helped
