I have never used iOS myself. I am just not a fan of Apple. I feel like it is overpriced. I have always used Android-powered phones for this reason. They are more customizable and I find they run better long-term. My Galaxy s6 still runs like new!
I think the price of Apple products were justified when Steve Jobs was still leading the company. The company has done a lot of technological leaps in their gadgets. Right now, I also think Apple products are overpriced because there is no more innovation done on the products but only upgrades.
