I would Suggest the CountorHD by VHOLDR. I have actually done a bunch of research online, no actual side by side comparisons on my own.
Keeping this story short... Last year after watching the F1 season I wanted to get a Helmet Cam for use in my racecar (however they are not allowed to be attached per SCCA rules) Either way I still purchased a VHOLDR camera and I LOVE the thing! I first discovered the Go-Pro because they advertise in Sports Car. I then did some more research online and decided I would contact VHOLDR before the go-pro based on a comparison of the 2 cameras.
I would look at both the GoPro and the ContourHD before you decide to purchase any other camera. For me the big wins were the ability to mount the VHOLDR anywhere at any angle in any position, it was much smaller than the GoPro, the durability of the unit after watching video of motorcycles crashing, the rechargable battery, the ease and simplicity of operation, and the ability to use it skiing/biking without the skips and misses I have experienced with other cameras. I actually went skiing up at sugarloaf and mounted it to my boot and it never skipped a beat! I can send you a link to the video if your interested.
They just came out with a new camera called the ContourHD. This is basically the same camera but upgraded to HD so you can watch it on your TV without the resolution problems you would get with the Go-PRO or original VHOLDR that I already have.
One other HUGE feature that they have that no other camera offers is an exclusive program/website that you can download your video to, edit and then share online with just 3 clicks start to finish! You can utilize youtube or any other site you wish however with just 1 click it is shared at VHOLDR.com

The incar video that I posted of Tim last week from the NER spring training was with the original VHoldR.
