What's the difference between the iphone 5s and iPhone 6?

I'm getting a new phone and i was set on getting the iphone 5 because the 6 is too big and won't fit in my pocket, but now people are telling me i should get the 6. So besides the look and size what's the difference?

note: please don't compare the iPhone 6 plus, and if you're planning on responding with any smart alec answers please don't bother answering

Honestly if they are both running iOS8, except for just a few small features on the 6 series, size is just it. If you've never had a 6 you wouldn't miss those features since the 5s can still do 97% of that stuff anyway. Best luck.

I would go look at it in the store and see what you think.
