Well I have just made the switch from android to iOS and have to be honest I am loving the iPhone 6 plus.
Years ago I had a 3GS and after buying an htc desire hd I swore I would never go back to Apple as I loved the way I could do anything on android. Forward wind several years and several android phones later and I have had enough of android, constantly waiting for updates and things to finally work properly, one of the most annoying examples of this is that I had my htc one max for 18 months and had been waiting 15 months for the sky go app to work on it whereas I bet it works fine on every apple device.
My swap to iOS hasn't been plain sailing as I had awful trouble getting all of my contacts on my iPhone plus was unable to copy messages over which I was very annoyed about and I am no safari fan as I much prefer everything in desktop mode, the stock htc browser is much better imo, then there is the hassle of custom ringtones etc but even after some of the hassles I have had I am very glad I made the switch although I do love my one max and were it not for a faulty switch making the phone difficult to wake up then I probably would have stuck with it.
