They both are similar. Android has settings in the apps, iphone some settings are in the apps some are on the settings app itself. They are very similar. Android has more options which can be confusing, iOS has less options which can be annoying. My biggest pain point is iTunes, since there is no other way to get your own music files onto the phone. But iOS is very straightforward, you won't have any issues!
