OnePlus 6T vs Asus Zenfone 5Z: Which One Should You Pick?

To sum up, both OnePlus 6T and Asus Zenfone 5Z are great phones offering value for money. But given the scenario of daily use and convenience, we will pick Asus Zenfone 5Z over OnePlus 6T for its excellent performance at the price.

OnePlus is slowly now exiting the entry-premium flagship range to enter the premium category.

OnePlus 6T starts retailing at Rs 37,999, while the base variant of Asus Zenfone 5Z costs 8,000 less at Rs 29,999. OnePlus 6T may stand a tad ahead given the performance, camera and new technology it has been updated with, but offering the right value for the money you spend on a smartphone matters the most.

Now some would argue then why not pay 8,000 less and buy Xiaomi Poco F1 at Rs 20,999.

See, Asus Zenfone 5Z is actually a flagship with some great specs and performance. Yes, Poco F1 has SD 845, but it still is yet to prove its worth as a true flagship. To conclude, Asus Zenfone 5Z can offer a true flagship experience at under 30,000 rupees, with no huge reason to spend another 8,000 bucks for a OnePlus 6T.
