The LG G3 has just about the best screen to body ratio of any smartphone. It has a 5.5" display and some devices with smaller screens are the same size or even larger.
Samsung's galaxy s series has changed a lot since the s2 and s3...
S7 is one of the best phones on the market right now. Touch wiz has improved a lot too. I was very impressed with last year's S6 and I was coming from a stock android experience.
it will be a bit tedious turning off the bloat ware but i think the more you use your new s7 the more you'll love it. The bloat ware is far less than the s3 days and at least one has the option to turn it off; there are stock apps on iOS I wish I could disable.
