Yeah, I'd agree with this. Apple and Samsung are in a league of their own now. They have tighter control over their own phones now and can properly optimize software and hardware.
However, do we have any info on the US variant of the S6/S6 Edge? Are we also getting the Exynos model or will it be watered down with a Snapdragon SoC, like it has been for the past few years? Samsung needs to push the envelope like Apple and release one model for the US that supports ALL our bands.
Samsung has been very vocal the last couple of months, dissing the Snapdragon 810 publicly. Samsung blames the overheating issues. And finally has their factories ready to pump out enough Exynos chips to handle a worldwide release.
