I can't say I'm very experienced with the different cameras but I'm using the GoPro with the handlebar mount. I like this option because I don't have to stick a mount onto my bike or helmet. It's easy to turn off and on when I want and I can flip it around quickly. I can use the handlebar mount in other places on the bike too, though I do have to put a piece of rubber or paper towel around the post to get a nice comfy grip.
The camera itself is not intuitive by any means. But once I forced myself to read the directions it's a piece of cake.
