I have an iPhone 5 and I love it.
I wouldn't even want to have a Samsung Galaxy s4 even if it's free.
Maybe it's just me, but I don't see anything that Galaxy has but iPhone does not.
For example, the Apple brand is already a luxury comparing to Samsung.
Apple iTunes have more apps than Android.
iPhone is a popular phone than Samsung.
iPhone's overall appearance is WAY better than Galaxy (that's just my personal preference).
iPhone has a better quality than Samsung (material-wise).
Maybe the only advantage that Galaxy has are that it has a bigger screen and faster processor. Besides that, I don't see why Galaxy is better than iPhone. Also, I think iPhone's screen is big enough for me and Apple processor is not slow at all.
So, I'll appreciate it if you can tell me why you prefer Galaxy over iPhone!
