Ha, ha! Didn't mean for this to be a trick question. I just happened to be looking at the two photos and was pleasantly surprised at how good the iPhone pic looked compared to the fancy camera system...
...drum roll...the bottom pic was done with the iPhone. The only thing that bugs me about the photo is the distortion caused by the little bitty lens. If you look closely at the front tire, it is not perfectly round. The color is really brilliant making the sky bluer than blue, but looks good to me.
For editing purposes, the top photo would always win out. There is more digital information with this photo and when I zoom in on the pictures the top picture stays crystal clear and the iPhone pic fades way pretty quick.
Nevertheless, the iPhone 6 has a pretty good camera and has the potential to give you a good photo...especially when there is a Valkyrie in it!
