What would you prefer? iPhone 6s Plus or Samsung S7 Edge? Plus points for the one with the most kid-friendly features.

We have both iPhone and Samsung at home. Few months after I gave birth, hubby was about to buy me a new iPhone as an upgrade. I really feel iOS fits my professional and personal needs but with our munchkin, it is very difficult to download and store apps and movies for kids. So I switched to samsung. It is better for me as I have an expandable memory, easier to share movies with co-parents, and I can choose several "Kids Zone" apps.
