First of all when, people want high end phones they come up in dilemma wheather to buy samsung or apple iphone
About samsung latest phone s6 and s6 edge comparing with iphone 6 and 6s
I would say if you want class then u should go with iphone. Iphone has following advantage over samsung
Class
Camera
Design
Looks
But if you choose of functionality you must go with samsung s6 as it is approx 10 to 12 k cheaper then iphone, it has 3gb ram and outscore processor for faster and better performance, while iphone comes with a9 processor, better life of s6 is better and more and good battery performance.
It lags ui same as in all device, wireless charging not that effective
After all its one’s choice which to go for.
