Listen mate, as much as I am an iPhone person I do really think there are good Android phones however these have the same price as an iPhone. So price is a bad argument to defend either side.

Build quality is a second thing, iPhones are made from high quality materials you won't find on your average android phone. iPhones are also 99% immune to viruses.

Android on the other hand has lots of customization options and a very wide compatibility. However that can lead to heavy software being ported onto a 100$ phone, which causes major lag.

The new Galaxy's are getting a better build quality each year, so the differences are being eliminated one by one. I might buy one in the future.

In the end it doesn't even matter which one you like it's all based on your opinion and experience.
