Replying to Sony Action Cam

Anyone use this for skiing? Thinking about buying one instead of a Gopro...was looking at some used go pros on ebay for the price I can buy a new action cam w/ so many extra accessories.

I only would use it for skiing. Worth it? Or should I just go gopro.

I had a go pro 2 (fell into lake deep down) and it was to heavy I thought and top heavy. Curious how the new ones are. The new small go pro looks pretty cool but reviews say it has worse video quality
