To me it's all about what best fits your personal needs. I bought the iPhone 6 on launch day and took it back a week later for a refund.
Since then I have bought a gold iPhone 6 plus 64 and I thought the device would be to big as my daily driver, but I find myself adapting to the device more every day.
I like the large screen for emails and text. Me being 58 and wearing glasses, the bigger the screen the better. I hear all the issues about bending the device but, I take very good care of my device and have never had any problems on any device I have had in the past.
I always tell folks when they ask me which one is better? I tell them to go to a store and play with a demo device, ask questions and get the one that best fits your needs, in the end, your the one that has to live with your decision.
