95% of sites don't matter, Anandtech clearly shows Exynos winning and they are known to be both objective and through.
All Exynos phones are clocked at 1.2ghz so that comparison is perfectly fair, why would a GS2 owner deliberately cripple their phones performance to give Tegra 2 a chance. Even if that was the case Tegra 2 still doesn't have NEON and it's media playback abilities are worse than Hummingbird, Exynos is on a whole different level in that regard.
The fact that emerging markets are the ones to get Tegra 2 Galaxy S2's while all of the top markets (USA,Canada,Western Europe, South Korea) get Exynos kind of says it all.
