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?

This is the best single-lens action cam you can get from GoPro at the moment in features and performance. Compared with the Hero 7 Black, there are a lot of feature tweaks and updates that make it just generally easier to use and a better camera, regardless of what you're shooting. But for those who use a GoPro regularly, things like the redesigned waterproof body that allows you to attach the camera directly to GoPro mounts, a customizable interface with shooting presets and improved image stabilization all add up to a worthwhile update. The lens is now made with Gorilla Glass that's twice as impact-resistant as the glass on past Hero models. Read about the GoPro Hero 8 Black.
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.

For a company known for its camera drones, DJI got a lot right with its first action cam. One of its stand-out features is its front color screen. It might be small, but it's enough to make sure you're centered in the shot when the camera lens is facing you. The view can be switched with a voice control. It's also waterproof and rugged with removable lens covers, it has great electronic image stabilization, shoots HDR video and has customizable presets so you can get to the shooting modes you want without diving into menus.

​​​​​​​A. It depends on how big of a memory card you use with your GoPro. GoPro cameras work with standard SD cards, which are affordable and come in all different quantities. In most cases, it pays to get a memory card with plenty of storage. GoPro videos, especially those shot in 4K, can produce especially large files that can eat up storage faster than you think. We recommend getting an SD card with at least 128GB of available storage.
