I'll look like I'm totally biased towards Drift because I have one but actually, I hate all camera companies. They never gave me proper support on their products.
Both cameras are the same, they use the same hardware with a few tweaks here and there so quality wise they stand equal.
I'd prefer the drift because of the form factor and the rotable lens. It's a life saver when you mount the camera in awkward positions. There aren't many mounting options with the gopros and they look silly, like a sailing foil when mounted on the side of the helmet. Also proprietary everything makes a GoPro a poor decision (proprietary mounts, connectors, accesories) and also the stupid cage that doesn't allow any accessory to be connected with the camera inside.
With the drift you get more mounting options, you can use common camera mounts if you don't like the clips included with the camera (it has a threaded socket you can use with any camera tripod or mount), you get standard connectors (HDMI, USB, 3.5mm for audio) and you can use the mic and data connection without problems with the camera mounted to anything and even with the back hatch closed using the non-waterproof cover.
