we have both phones in my household. both phones are excellent. i lean toward the apple (i.e. as I use that platform and like it). my wife likes the galaxy as she is a pc user. there is plenty of room for both phones in this marketplace. apple stock is easily worth 600 or 700 bucks, and will head there eventually.
Good luck. I gave up an old Samsung which was a POS for an i phone 5 10 days ago. It's a wonderful phone, intuitive, easy to use and flawless. Don't know how I lived without it. You can keep Samsung. And, for disclosure, I own no AAPL.
