Which is better - iPhone 5c or 5s, or maybe Samsung Galaxy s4?

I would like to know which one of these is better. But Please DO NOT ONLY WRITE THE ANSWER DOWN, I NEED TO KNOW WHY IS THAT PHONE BETTER THAN ANOTHER.

Depends on how much you wanna pay but I would say the 5s
The 5c is basically the same as an iPhone 5 but plastic and I don't think it looks that nice tbh
The 5s has the touch sensor thing which everyone hyped over and it comes in cool colours
The galaxy s4 is a good phone as well apparently but it's like massive and on android which is just ew.

5s

performance, battery life, camera, build quality, etc

The Galaxy s4 is better because it has a better and bigger display, has a faster processor than the rest, the camera is better, the battery lasts longer. All this is evident in a comparison of all three phones here

Ignore the security, Galaxy S4 is the best.

Galaxy S4 because it has Android so it means you can customise it and has all these extra features that the iPhone doesn't. If you don't like the plastic, get a HTC One. And people saying stuff about security on Android- it's fine. Never have i used a security app on my phone and i have downloaded apps and stuff from websites and never had a problem. Also battery life will be better on an S4. Camera is 13MP and really good, although 5S camera is good too (but personally i prefer the 13MP for cropping and zooming purposes).

I would choose Android because there are better apps available.

Well each phone is different, in my view iPhone 5s is best among the three coz of its premium feel and compared to android its secure(though BB is best in security) and its new is more appealing its product service best and itsapps less buggy compared to Android s4
if you consider some trendy look then go for s4 or IP5c
