haha the reason why I feel they're very different is because the Canon has a muddier image, which is nice for achieving the grainy filmy look. Also, it shoots 30f mode, which interlaces the 60i image differently to mimic a progressive frame rate.
The vx series produces images that are much sharper and more video-ish. Since it only shoots 60i (aside from the useless 15f feature), I found it to be much better for the digi/skater look. You can get much more accurate colors with the VX, whereas the GL2 is a little more chaotic and harder to tame.
