I actually like the Crossfire better. But the Diamondback seems to be a little higher quality. They're lighter and a little clearer. But the problem for me is that the diamondback isn't as nice to use with glasses, which I wear all the time. I'd be willing to trade my Diamondback 10x42 for Crossfire 12x50 straight up. That would be like at least a $50 discount if you paid 170 for new Crossfire's and traded for my lightly used Diamondbacks.
