What phone should I buy ?

Hello fellow readers of The Verge !

I am wondering which phone buying. My ideal specs for a phone are these:

With a budget of $600 off contract

A really good and fast camera ( i don´t mind the megapixels ).

Pure Google Android ( 4.4) or iOS

Nice and utilitary design, i prefer aluminium.

A 1080p 5" screen.

I am stuck within the iphone 5s, or waiting for the 6, the HTC One (m8) Play Edition if there is one or the Nexus 5.

Tell me what you think and Thank You!!
