Iphone 5s vs. 5c

OK, I've been using the same htc phone for almost 4 years, and the screen is shattered, and it's on the fritz! I need a new phone and it needs to last through Seth's MBA and beyond (I'm hoping for a good 3 years on this phone) I am switching to iphone for the music capacities and such, and I want to be able to blog from my phone (upload pics and vids easily from the phone). I want it to take great pics and vids of John who is constantly on the go. And I really don't know how much memory I need. and really, other than finger print sensor and the fact that it looks better and is all metal, is the 5s even better? So, please give me your thoughts on iphone 5c and 5s!
