Slightly used iphone 5s or new 5c?

So I'm looking for a new phome and I was offered a Iphone 5s used for 6 months and a new iphone 5c for equal prize, which one should i take? Can someone compare the two models?

I had an iphone 5c for about a year and a half and it was a really good phone, the 5s and 5c are really similar but the 5s has slow motion on the camera where as the 5c doesn't. I just got a 5s and I think they are both equally good phones so whatever one you would prefer i think the 5c is more curved than the 5s. If you're getting a phone case the 5s and 5c have some buttons in different places but thats it really. But in my opinion they are bother really good phones

New 5c the only difference is touch thing

I would take new always, that way there's no question on whether it was ever dropped etc.
