Well, I already checked the business and ultimate versions in my own pc. And I also saw the home premium one in one of my frinds' pc. As I got only 512mb ram it was slow on my pc. But the real question is what is the best edition of vista? Why is that particular version of vista best? What type of PC configuration does that need( Higher or normal)? What type of user should use that?
