Im going for the Snapdragon... at the minimum it should be equal performance. But it could have instances where its faster.

Qualcomms 28nm machining is very efficient, I'd say slightly moreso than the Sexynos. On top of that, 4 cores will have same performance as 8 but will sip power even less. So even more savings.

On top of that the NOTE 3 (Snapdragon version) will be the first one to utilize new technology to sip less power from LTE connection.

But the most important thing is software. The Exynos is bound to have more development as that will have more users and developers. If the QSD gets as early leaks, or driver support is tiptop then this should provide parity. I don't see why software wise one should get an advantage over the other, but this isn't what history's shown.

All in all, you can't go wrong with either...but it seems the QSD 800 has a distinct edge.
