If you are iPhone user, then stick to iOS. Long term iPhone users mostly do not adjust well to Android.
Android is good for the most part, but not as refined as iOS. It's unpredictable, like occasional software glitches, battery drain, stutters etc and i have seen that to happening more with Samsungs.
Yes, it's gonna sell at loss. Androids lose their value almost twice fast as iPhones due to higher competition.
