OK, here are a couple of pictures from each taken in my garden. I'm using standard settings on the iPhone 5 and HTC One barring both have HDR enabled. I've made sure that both of the pictures were taken from the same distance away from the subject too.
On each of these first two pics, the focal point is the flower at centre middle of the frame.
The focal point of these next two pictures is the closest knotted right angle branch.
I honestly prefer the HTC one pictures. The colours might not be so bright but I feel they are more natural given that I know what the original scene looks like with my naked eye. I'm afraid you'll have to take my word for that, sorry.
Anyway, in comparison, I really do think the HTC One has the better camera.
