I have a gopro 3+ black edition ( the best from 3 series ), it has the remote, which is good for me, I think 4series did not come with the remote but had a screen on the back of the camera, not totally sure though Could be wrong. anyways mine is great for quality etc, the newer ones have better fps at higher resolutions, thats pretty much it. I hardly use mine so I cannot compare batterylife etc.
