Well thats your opinion, imo, why would anyone buy the iphone6 because its the iphone 5/s plus half an inch of screen.
What are you trying to say? If that's the case, then the 6 PLUS is a 5s with 1.5" extra screen considering the fact that the 6 and 6 PLUS seem to perform almost identical. Unless you want to consider all the people complaining that the PLUS is choppy and the battery life isn't as great as they thought it would be
Looks like your "flagship" phone is being out performed by its little brother and you can't come to terms with it.
