Are you an iPhone or Android user?  What are your favorite features of each?

I personally own the iPhone 6S and I love it.  I've been an iPhone user since 2008 and did the old Android experiment back when the Galaxy S3 came out. 

For starters, iOS runs so much faster and without lag like I experienced with Android.  I like a phone I don't have to do anything to and Apple pretty much made that. 

The new camera on the S versions this year is pretty outstanding.  It was rather frustrating that Apple put the same camera in the iPhone for four years.  This year's is no joke.  The FaceTime camera is also HD now and looks pretty good.

What are your preferences?
