I am making the switch to iPhone too. I have used note 3, battery drained super fast.
Honestly dunno why TS asking for comments from others to convince him to change. The device value and worth differ for everybody.
A $7000 vertu might suits your needs and meet your value. It will not for the average joe. The social and productivity value you get from the phone of your choice should define what you buy.
I for one is switching back to ios after trying out Android.
