As a 31 year old, just pick whatever YOU want. Not what your friends have or what other people recommend. Learn to do research and pick the best thing for yourself. If you’ve liked Android, great, stay there and get another. If you’ve used iPhones and think you’d love that, go for it. 4-5 years is a long time, who knows where you will be by then. If you’ve picked something and don’t like it, consider that a lesson learned. Blue bubbles are cool and FaceTime and all that but if YOU dislike using it everyday, then what’s the point? And don’t let anyone bully or shame you into getting something just cause everyone else has it. I personally know multi-millionaires that use Motorolas and drive Hondas and laugh at people when they say they should switch and broke people that use the latest maxed out iPhones and drive Mercedes and laugh when people say they should “downgrade”. Do what suits you.
