HD Cameras, Sony vs. JVC

I cant decide which to get, I played with both of them at best buy. I love the JVC camera lot more, but i hear it has really poor image quality & the whole .mod files with videos.

Sony on the other hand, is a lot more and im not sure I want to spend that much for the camera, i havent been able to find much reviews online for it.

Which would most people rather have? I’d be using it most for my band’s shows, just recording us live & such, thats all.
