most users pick samsung, i pick samsung too.
use to the menu that most other users do, would not get too wrong if using it.
samsung's design are more classy, elegant. sony's are often a bit too young, advanced, experimental. front/ back full glass etc. non-removable battery. I would not switch to sony in foreseeable future. releasing 6.4" phone is kind of question. i wonder what is this company thinking. not considering how a user actually use the device? i could not trust its design and get its product. if it has full range: 6.4", 6.1", 5.8", 5.5", etc. it is a different story.
samsung's success is it has the most complete range, better suit more user's need. having consistent designs over the years. once used to it, keep on using it. until this brand turns bad severely. like the previous Nokia.
