I use both iOS and Android....I like having two different phones at any given time and have been doing so for years now.. That being said, my iPhone is my daily driver and I prefer iOS, especially for taking photos and video. There is something about the iPhone and the camera app software ease-of-use that for me and my needs, cannot be beat.
I go to Disneyland every summer (I am 40, and yes, I am big kid at heart) and cannot stand to be without an iphone to take my pictures and video. Last year was the first time I was not able to take an iPhone with me and ended up having to use a Galaxy S4. I was not a happy camper since that GS4 gave me alot of issues while on my trip. As soon as I got back from my trip, I sold the GS4 and picked up a 5S at cost to take the edge off lol.
