What's better? AMD Mobile Sempron or Intel Celeron M?

Celeron, runs cooler and give better battery life span.
honestly... i wouldn't get a Celeron if my natural life depended on it. All they are is a CPU made with the cheapest parts... by the lowest bidder. I see Celerons as the payless shoes of CPUs.
I find solid performance out of the Sempron CPU. the Celeron tend to show its weakness a bit too normally.
Intel Celeron M is better than AMD Mobile Sempron.
