That was one of the most thorough comparisons I have ever seen. If anyone is considering an iPhone vs Galaxy S6, this is the video to watch.
A couple thoughts...
He said at the beginning that his phone was slightly bent. I could not see it in the video, but this IMO is unacceptable. I have perused the iMore forums for the 6+ bending issues, and they are firmly of the belief that this is always user abuse of the device, and nothing wrong with the manufacturing. Take that as you may, but this is not the 6+ it's a regular iPhone 6.
The Samsung did seem to have better viewing angles. This was apparent when he put both down in landscape. Though to the iPhone's credit it was at a greater angle so that is to be expected. Regardless, the S6 had the better viewing angle no question.
Let the pitchforks fly ... because I truly did not realize how similar the two phones were until I watched this video. Not just the bottom of the phones, but the actual software and user experience. Say what you may, but Samsung definitely copied Apple here. If you can't see it, then maybe I am just nuts. The Parallax wallpaper? Come on man! If you think Samsung did not copy Apple, you are delusional.
With that said, and after watching this video, I am really torn between these two great phones. The iPhone performs on par with the S6. The camera and video was very similar (even though I am not a fan of 8MP c'mon Apple WTF). The Screen on the S6 is killer. The idea of Themes are killer. The Apple UI is killer. iTunes I'm sure is still a pile of poo. I think if you flipped a coin you could not go wrong with either.
