Much like Band-Aids or Kleenex, GoPro makes products so good that their brand name is synonymous with the product itself. GoPro’s portable video cameras set the standard for action cameras: they’re durable enough to withstand just about any outdoor activity, they’re easy enough for anyone to use, and they include features typically reserved for far pricier cameras.
The reason I ask what you will be using it for is to determine which set of features you need. If you're going to be using it for simpler activities, don't go all out for a Black edition with a 60fps, 1080p cam (all HERO3's are 1080p, anyways). The reason the Black Edition is so expensive is because of the crazy quality it has, and if you're using it for a more simple basis I wouldn't worry about the difference. The Silver or even White is perfectly fine for you. The main difference between these two is the white's camera has a 5 megapixels with 3fps burst while the silver is 11 megapixels with a 10 fps burst -- is that worth $100 to you?
Is GoPro still the best action camera?
But it’s not only the lens lending credit to the impressive video GoPros capture. GoPro’s new Hero6 Black captures 4K video at 60 frames per second (fps) and Full HD 1080 at up to 240 fps. This isn’t just impressive for such a small camera — few interchangeable lens models have achieved 4K/60, with the $2,000 Panasonic Lumix GH5 being the first. As for still photography, the Hero6 shoots 12-megapixel images with features such as WDR (wide-dynamic range, GoPro’s lingo for high-dynamic range or HDR) and RAW file capture. And a new image processor — a first for GoPro cameras — helps improve performance and image stabilization. GoPro has managed to put all of this into a camera that’s not much larger than most DSLR batteries.
