Benchmark: Waterfox vs Firefox

Normally I don't like modified browsers. With the "official" browser, I'll get the newest updates as fast as possible, so why should I change? Well, according to Waterfox I will get a faster browser:

“Waterfox has one thing in mind: speed.”

But is this true? I've seen so many crappy modified browsers, so I've decided to give Waterfox a test.
The newest version of Firefox x64 is "13.0a1" and the newest version of Waterfox is "10.0". Futuremark's Peacekeeper looks like a trustworthy benchmarker, so I gave it a try;

Waterfox 10.0	2144 (+/- 16)
Nightly 13.0a1	2099 (+/- 14)

(Results on my PC).

So Waterfox might actually be worth a try!
