GoPro or Nikon camera?

Give me some feedback please

It really depends. GoPro is a wearable sports camera, whereas Nikon produce high quality photographic cameras. You need to specify your needs for the camera: photo or video or both and how you will use it! If you want to strap it to yourself and jump off a cliff then get a GoPro, but if you want to produce professional looking photographs then Nikon is proberly better. Please add more information!
