Which is better? Samsung galaxy S4 or the Apple iPhone 5S?

In terms of look and desing the iPhone 5s is definitely better, but in terms of almost everything else and that includes the specifications and cool features the S4 wins. Here is a side by side comparison of both the phones: - If you want to look at some consumer reviews of the Samsung Galaxy S4, you can do so here

I would say its an even tie. It really just depends on the user, some people are apple, some samsung

The iPhone 5S wins on looks & performance.

Of course aluminum/glass/stainless steel beats plastic & fake metal (looks)
