GoPro has never been the best, they just have a hell of a marketing budget.

One I'm looking at right now is this one: http://a.co/eCn3qhK

6 hour stated battery life, 1080p, nice mounting profile (versus GoPro "strap a brick to you" style)

Also that version has an enhanced nighttime sensor that they claim is better than the GoPro Hero 4 Session.
