Samsung has sold over 10 million Galaxy S4 handsets worldwide, making it the company's best launch tally to date. That kind of popularity makes it the bees knees in the Android market, but overall? It still has the iPhone 5 to contend with, which, even eight months after the handset's initial launch, is one of the hottest devices money can buy. So it is only fitting we pit the two against each other; mano-y-mano.

Out of all the big rivalries—Lakers vs. Celtics, Tottenham vs. Liverpool, PlayStation vs. Xbox—Apple against Samsung, or visa versa, is probably the biggest of them all. For the most part, the two companies are synonymous with the mobile market; the landscape as we know it wouldn't exist without either. The two are in a constant Keeping Up With the Jones' battle, and will always be compared, forever. This versus isn't a thesis on which OS is better, or the two companies as a whole. We want to know, plain and simple, which device reigns supreme.

Samsung Galaxy S4 vs iPhone 5 Gallery

As we mentioned before, the iPhone 5 is relatively old as far as time on market is concerned. But having just launched on T-Mobile, the device is definitely one that customers will consider, and especially one that will vie for sales against the S4. There are rumors the iPhone 5S is imminent, meaning the iPhone 5 is coming to the end of its cycle as Apple's flagship. The S4 is Samsung's big flagship now. Be that as it may, the iPhone 5 is still easily one of the best handsets out there, and can more than hold its own against the Full HD revolution.

Probably the biggest disparity between the two is screen size, which has always been a sore subject for Apple fans. Whereas the iPhone 5 has a 4-inch display (326 PPI), the Galaxy S4 has a 5-inch screen (441 PPI). Size of the screen comes down to preference, of course, so that might be a negligible comparison. However, there are some obvious spec differences, such as the S4's 1.9GHz quad-core chip, 2GB of RAM, expandable storage and 2,600mAh battery. That, too, might not be a necessary comparison for the average consumer. To the die-hard tech fan, though, that's all that matters.

For every blazing spec, it must be noted that the iPhone 5 still has superior build quality. What it will ultimately come down to is which device provides the better experience for you. Samsung has worked very hard to introduce features aimed at attracting the average consumer, while Apple's ecosystem still provides one of the easiest pickup-and-go experiences you'll find.

Once the iPhone 5S launches, the comparison will be a bit more even, at least as far as time on market is concerned. When that happens, the Apple/Samsung rivalry will be just as strong, and battles between the two phones (and companies) will continue on into eternity. Right now, though, which device do you prefer?
