I've been trying to decide which one of these would or does give the best results, so far i'm bought into the idea of the GP h3, as it definatly seems better underwater, but I can't help thinking the picture quality is better from the Sony action cam for land use, and I quite like their steady shot funtion, but all my research leads me to think the GP h3 would be better in the long run, any thoughts on this comparison vid much appreciated.
