I think the GoPro has the edge over the Contour in terms of functionality and ability to take abuse. The Contour is sleeker and doesn't look as dorky and is noticeably lighter. Here's my side-by-side comparison
. The regular contour is being blown out right now for under $150 as much as I like the idea of GPS, I don't think it's worth 2x as much as the regular. The Contour+ goes for $500 and although it has some new bells and whistles and a wider FOV, I'd probably save the money and just get the regular Contour or the GoPro.
