What's so good about iphones, and which is better?

I can upgrade my phone to an iphone 4s for 180$ or i can upgrade to a 5s for 265$ which should i do?

Go with the 5S, it has a lot more options for it plus if you decide to switch carriers, you can get more money for it. I used to be 100% Android guy but every android i had, i got A LOT of problems. Software/app crashes and the device locking up. Since i switched to iphone, i haven't had any problems. Also 5S is a lot faster then the 4s

For $85 more, I would go 5S… If money is really tight then 4S is a good option
