To get right to the point of my writing: I can't give you a definite answer. What I can definitely tell you right now is that we are to focus on the GoPro HERO4 and HERO3+'s (and I will touch base on a few HERO2 and original 3's as well), as it is the best technology and provides options for numerous consumers. With the recent announcement of the HERO4's especially, we'll tackle the main features of those to help you decide if that hefty price is worth it.
Some GoPro cameras have user-replaceable batteries, and some don’t. If you need a camera for camping or several days away from home, you’re going to want the former. If you buy a GoPro camera with a swappable battery, you can keep extras with you, so you’ll never miss filming the perfect moment. On the other hand, if you’ll only be using your camera for an hour or two at a time, you can save money by getting a model without a user-replaceable battery.

The brand new Hero 4's are even more powerful, hence the hefty price of 5 bills with the HERO4 black. They come in either a Black or Silver Edition; however, there's also a new budget-friendly choice called the "HERO" which has some essential features to work with at around $130. I love the fact that GoPro brought this into the market to give us a choice -- i'll be buying a few of my friends one for Christmas.
Although obvious, I put this here first because this is one of the most important factors when purchasing your camera. The HERO3 has three editions (white, silver and black), ranging from $199 - $399 (prices continue to drop annually as newer versions are released -- we'll keep you updated on those). The HERO2's are at the bottom of this gap, but aren't as "new" and lack some features the 3's have (they're discontinued at this point but can be found on the net here and there).
You get many of the same shooting modes you'd find on a GoPro device, such as time-lapse photos and videos and slow motion footage at 1080p at 240 fps, and there's even a Drive mode so you can use it as a dash cam when plugged into your car, automatically turning on when you start your car and off when you stop it. It's not waterproof on its own, but a dive housing is included as well as several mounts, two batteries and a charger that simultaneously powers up both packs. It also has built-in Wi-Fi so you can connect to a smartphone and use an app to control the camera and transfer your shots for sharing.
