Which Windows logo do you like the most?

Which logo do you like the best?

I grew up watching Win98 boot up with the classic Windows logo, so there's a place in my heart for it. However, I think the Windows Vista/7 logo is the most aesthetically pleasing. What do you guys think?

Windows Vista logo is the best, IMO. It's basically the Windows XP logo, but some-how different. The colors look better to me too.
The Windows 8 logo looks like it's just the Windows XP logo, but someone flat ironed it..

#2 and #3 are like so similar, if not the same. So either one of them I would go with
