thats why you need to see what you really want.
if average use with light gaming then 6 is enough already.

but afterall, see how much you willing to fork out for a phone only.

6 and 6s camera very minimal difference only.
unless you're professional photographer who knows exactly what you're doing.

if not average joe like us who only take photos and post on fb/ig even 5s is more than enough already.
