Which one should I get, 32 gb iphone 5 or 16 gb iphone 5s?

I have a 5s. It's great however… I think the operating system is a little laggy and tiny bit delayish. On the iphone 5 it isn't delayish at all in my opinion. I thurougly know the difference between 5s and a 5 but I just would like to know what you guys think. My 5s is a month old and the 5 that I might get is brand new frommy friend that works at apple/ please tell me what you guys would do if you were me

Oh and I have also been having some stupid problems with my 5s that frustrate me. Example it always randomly shuts off, it crashes etc.

32gb 5

Whatever makes you happy. The 5S hardware-wise, is better though.

32 gb iphone5, as your old 5s has some problems. So if you are getting a new fresh phone then why care about the old 5s. I hope that helps. You can also buy a 5c as it is also very good.
