Although Sony's mobile division has been dangling at best, that has not stopped the company from coming out with some impressive devices. Last year, the company launched the Xperia 1 II and Xperia 5 II. Today, Sony is bringing out the predecessors Xperia 1 III and Xperia 5 III, two flagships made for people who want everything in a phone.

The Xperia 5 III is the one you should be going for if you are looking for value and a smaller sized phone, but if you want the larger phone with top-of-the-line specs, then the Xperia 1 III makes more sense.
