I liked the GoPro Android software better, and the Sony remote, which has a viewfinder built in, wasn't attractive for our use cases. I'd rather have a better app.

Also, the wider field of view on the GoPro without built-in stabilization works better for skiing than built-in stabilization that can sometimes fail to keep up. Aesthetically, I just prefer the wider field of view. A better camera operator might be able to do more with a narrower FoV or even a zoom, but the GoPro is almost always better in practice.
