Do u know if Windows 7 is beter then XP

Hello fellow Linux users, yes I am bored but also I am wondering if Windows 7 would run better then XP in virtualbox, I have being running XP to update my iphone with music, but in XP it takes very long.

So I wonder would Windows 7 be better suited or not, or should I run OSX? You know I would really love if u could update iphone just in Linux, but Apple just doesn't provide drivers for Linux.
