Here's a video comparison of the Voyage and the Glo HD. I suggest not taking these guys too seriously because they have a way of not quite knowing what they're talking about at times, but they do their best and I suspect they mean well.

As I watched it I had a good chuckle at they way they try so hard not to show their biases. The biases still come through just fine anyway. They really do try hard to be fair and they fail miserably and it's kind of cute. I always enjoy watching these guys although I'm not completely convinced they're real people. Still, they're easily the most entertaining cartoons on the internet.
