What phone should I get? IPhone or Galaxy?

I'm probably not going a new phone for a while now, maybe sometime next year, but I'm still going through my choices because I have nothing better to do._.
If I were to get a new phone, it would be between the latest iPhone and latest galaxy, which would probably be the s7 and iPhone 7 or 6S still idk. But I'm more or so just interested in which os you think is better. I've had the s5 for a while now, and I have nothing against it since I downloaded a whole different launcher for it, but I think I want some change. On the other hand, a lot of people seem to be buying the s6, so that makes me want to consider the s7 when it does eventually come out. What do you think?
