Realistically, if you're waiting for the fall anyways - there are going to be several other devices released between now and the iPhone 6 which would make the comparison much more interesting at that point. If you're in the market for a device right now, the M8, S5, iPhone 5s, Moto X, LG G2 and Nexus 5 are the best available (not in that order by any means). What are you looking for out of your device? Newness? Or is there something you like/dislike about these two that isn't being addressed by some of the other devices?
