I have never tested a GoPro. Here is what I believe any stand alone camera comparison looks like to the Sena 10C Evo Bluetooth
1. The Sena 10C records the audio off your mic as you are taking video so if you are narrating, it is laid down in real time.
2. Any stand alone camera will be out front and should be taking a full view picture or video. The 10C always has the side of your helmet in the field of view. Maybe a good place to sell advertising if you have a big following???
3. Cameras don't send music, turn by turn directions, intercom conversations and phone calls inside your helmet.
I haven't tried the Sena 10C off road yet but I purposely road my Venture on some pretty broken up pavement and the video was stable to my eyes.
