Drift hd is probably best.remote lcd screen for editing,stays on the side of the helmet so less likely to be knocked off and better shape.
I kind of hate the square look on the gopro.
Ok for proffesional work and mega slow motions yes but (who is editor by trade?)
Drift is having all I want to eaay make a film wihin one night without the heavyduty programmes and spending days to work it out.
