Win7 - Any differences from a CoH PoV?

I'm building a new computer and putting Windows 7 on it (currently using XP). I have the ability to buy Home Premium for $30, Win 7 Professional for $40 or Ultimate for $50. I've heard that for my purposes Ultimate is overkill but, from a City of Heroes point of view, is there any reason to choose Professional over Home? Or for that matter Home over Pro (bugs, errors, etc)?

Nope.
