ios is better for battery, far superior on privacy, and if you're anal about certain features like how apps sync (e.g you're on a really small data plan) you're better off on ios. but the variety of apps you can use from a purely "power/sophisticated" user's perspective, android's apps really blow away ios.
e.g. textra vs native messaging apps.
imessage vs pushbullet vs airdroid
people dont forget to set the dpi to 640 on the galaxy s7/e. really makes a big difference wrt using the screen size efficiently.
This is far from the truth. iOS is way more secure and has better privacy in their security than Android. There is a reason why they have been 2nd best to BlackBerry over the years and Android just recently got more secure on Samsung phones at least.
