I prefer the Start Menu in Windows Vista over the Start Menu in Windows XP because of the search functionality and the sorting order of files and folders. However, I prefer the easy of use of creating new folders in the Start Menu in Windows XP. Also, the recently used programs in Windows XP doesn't get cleared after a while like in Windows Vista. In other words, it's hard to choose between the two, but if I have to choose, based on the easy of use, I would go for the Start Menu in Windows XP. I wish they would fix the "flaws" which I mentioned above for the Start Menu in Windows Vista, which would make it the winner for me.
