What Phone Should I Upgrade To?

I have a 5 year old iPhone 4S that doesn't work anymore. I plan on upgrading my phone and I was wondering what phone I should upgrade to? I need all factors considered in answers.

If you're very used to iOS, upgrade to an iPhone. IPhone 7, 6 or if you want to keep the small size, iPhone SE. If you want to try out something new, go for an Android. They are pretty good too.
