Sony Xperia Z4 vs Samsung Galaxy S6 vs HTC One M9 specs comparison: a Mexican standoff

Sony is the latest manufacturer that refreshed its upper echelon portfolio, as its Xperia Z4 just popped up and relieved the Xperia Z3 from its flagship duties. True, it's pretty much an incremental refreshment and doesn't bring anything strikingly new to the mix. Instilling a noticeable "deja vu" feel, the Xperia Z4 is the latest embodiment of Sony's time-tested OmniBalance design language paired with respectable hardware.

Still, are the subtle hardware changed in the specs sheet enough to ensure the Sony Xperia Z4 a more prominent spot on the market scene? With rivals like the Samsung Galaxy S6/S6 edge, the HTC One M9, Apple's champions, and undoubtedly, the upcoming LG G4, the Xperia Z4 will have a hard time competing with the top dogs. Then again, it's a device that will certainly attract a host of admirers with its slim, metal body, and sleek OmniBalance design.
