Now we come to a very interesting part where we should say what OS is the best. This is very difficult because both OSs have faults and advantages. As much as Vista looks dazzling and fancy, it is more stabile OS than XP and also can handles better “sloppy” users. But then again, that big “BUT”. XP still has on its side better performances and better support! You will have to decide by yourself what finalist is better. If performances are all that you need, than regular XP is still without rival.
