I just bought the Gopro Hero 5 Black:

I almost went for the GoPro 5 Session, but I did like the 120 frame per second option on the Hero Black.
I'm not really a GoPro fanboy, it's just that I have my drone that shoots 4K at 30 frames per second, and my last GoPro didn't, and it made it difficult to merge Drone and Gopro footage into the same video trying to match the size and frame rate. This is the main reason for the purchase.
Anyways, I'm happy with it, and even though I've got a ton of accessories and mounts, I couldn't help buy another bulk accessory package for 6.99. Yes, 7 bucks on Amazon gave me all of these mounts, I couldn't pass it up. The Chest mount alone goes for 40 bucks, so I couldn't pass it up.
