I don't have a white, but a 3 black, and the sony. So it would be unfair of me to comment on the video quality
I got the sony first before the 3 came out.
The sony is an awkward shape for most purposes except side mounting on a helmet, where the gopro starts to get awkward. I tried chest mounting the sony, but it just pokes out too far levering up and down. I used a gorpo chesty with a tripod mount to gopro mount adapter, so maybe here is a better way now, but will still have to poke out too far, it has such a leverage effect that the gopro chesty straps stretch and move when hitting bumps.
my sony housing also encroached on the field of view of the camera, you could see a smudge in the corner of the frame when using the housing.
Not sure how much sony have improved mount selections, but gopro is very well catered for.
I really wanted to like the sony as gopro were ruling the roost, but they work very well. I love my 3 black, I haven't touched the sony since getting it last year.
There are far more choices these days for action cameras though and I am out of sate on that as I am not looking to replace my gopro yet.
Hey guys we've got a solution for the Sony (or GoPro). It works great with the Sony - you can mount it on your chest, shoulder, even your hip. In front, beside or behind you. And it's super stable - the camera doesn't flop around like with other chest mounts.
