Which helmet cam do you prefer?

I've seen several people on here with GoPro cams. Does anyone have experience with Contour cams, or have used them both?
Personally, I bought a contour because it seemed a little less bulky in size. Have mostly used it for snowmobilng, and have been happy with it so far. Just curious what you all think.

I have a countour and it works well.  I just wish I could figure out how to turn off the chime when I activate it!
