Which benchmarks are you looking at? And are they actually JSC vs SpiderMonkey or JSC+WebKit vs SpiderMonkey+Gecko? I.e. are they JS benchmarks or DOM benchmarks?

"Beats" might be too strong a word :). I guess the picture from AWFY 64-bit is that both have strengths and weaknesses but overall they're comparable.
Yeah, on that set of benchmarks (the one that everyone is targeting hence not doing anything obviously stupid on), they are.
The problem is that all of the JS engines involved have various failure modes in which they end up way slower than the others, though... We're talking 10x-1000x slower. And the problem with performance is it only takes your script hitting one serious performance bottleneck to make the speed of the rest of it not really matter. :(
Hence my interest in testcases that point out such performance cliffs, so they can be removed.
