Snapdragon vs Exynos is what it is.
I looked at importing a Snapdragon but i wasn't prepared to import a Snapdragon variant and accept no Samsung Warranty as a risk.
Also some have experienced network connectivity issues on imported phone's.
As far as i can tell from looking at material online and YouTube videos the Snapdragon gives approximately an hours more usage time and handles extended gaming better and heat control than the Exynos version.
That said some Snapdragon owners have reported similar battery output to Exynos users !
My opinion is that Samsung should stick with one chipset globally or allow a person to choose at the ordering stage.
