The Galaxy Note 4 took top honors with 86 out of 100 satisfied customers while the Note 3 & the S 5 were tied with 82 out of 100 on the satisfied scale. I might add this survey was conducted in America.
My S 5's a great phone. Battery life is even better with Lollipop update. I'm on AT&T and call quality is very good. No lag issues here and the camera compared to the One M8, well there is no comparison.
