I own Apple IPhone 6s from 1 year and never disappointed with it.As Apple products are pretty famous for their new innovations, Premium Quality materials used for manufacturing mobiles, Quality apps, Great optimization, software reliability, High security, multi touch, Voice assistance, Applepay, 3D touch, live wallpapers, processing speed, Solid design, one can buy it with no confusion from other branded ones.It has little cons too.Screen size, No 3rd party apps and accessories support and High cost than other competitors.
I finally conclude to say is, it is more reliable for professionals and who need to get an official branded look.
