The main differences between the Samsung Galaxy S4 and the iPhone 5s come in a long list, but the choice depends on the priorities of the user.

The Samsung Galaxy S4 is considered to be the most improved of all Samsung Android handsets. This is not just because of its bigger and clearer screen but also for its other features like the 12MP camera and the TouchWiz.

According to Alex Dobie's review of the Samsung Galaxy S4 that was featured in Android Central, the great Samsung handset is considered an all in one "ergonomic" handset package. Dobie described it best for its widespread availability with its most recent Android version working on its favor. He added that its TouchWiz UI may be a new thing but its poor design can still bring confusion to several users. Not to mention its cheap looking plastic chassis according to the reviewer.

On the other hand, just like the Galaxy S4, Apple's iPhone 5s is such an effective move for a huge upgrade from their last iPhone version. Rene Ritchie reviewed the iPhone 5s in iMore giving emphasis to its performing much faster for its newer model. Other improvements can be noticed with its camera that has the 120fps slow motion feature, the presence of the iOS7 and of course, its Touch ID fingerprint scanner.

If there's a bit of a drawback to the iPhone 5s mentioned by Ritchie, it's the fact that it did not change a lot with its screen still at the same size but comes with new colors. As bottom point though, the latest Apple smartphone emerges as a technology leader once again in the niche it belongs to.

As for your own decision, you can go for the Samsung Galaxy S4 if you want a smart phone screen that is bigger and if you want more options for customization. But if you are after experiencing the latest iOS in the world of smart phones today, then the iPhone 5s is what you should get. Remember that more flexibility can only be offered by Samsung's Android system but if you want an exclusive operating system but assures top of the line apps and other accessories, there is no other phone to go for but the iPhone 5s.
