If you are not worried about the apps then the 830 is a much better phone. Bigger screen, better keybord. The screen is also much more usable in sunlight. And the most important thing : Battery life. With my iPhone 5, once unplugged at 6:30 AM, needed to be recharged at around 4:00 PM the same day. With the Lumia 830, I am getting a comfortable 2 full days (unplugged at 6:30AM and recharged at 11:00 PM the next day. The Lumia has a much better camera too with OIS. Expandable storage up to 128 Gb and list goes on and on. Got to get used of the size though compared to iPhone 5s...I switched to Nokia with a 635 in September and was getting a 830 a month later and not regretting it.
