Here are scans of a MX 4 & GS III comparison in the local tech magazine, e-zone. Magazine is in cantonese so I'm just going to put this out there: the Meizu wipes the floor in the Audio department. Reviewer found the GS III to be very lacking compared to the MX 4. Not to mention that both devices run on the same Exynos chip, ie: same Wolfson. Now that the Meizu has the Play Store and is available in English, it can now be considered as a true high end phone.
I'll translate later~
