Vortex hands down. I've handled both, and the Vortex is extremely nice. The fine focus is a huge plus over the Swaro, and while I didn't take the Vortex outdoors, there is nothing to say that the newest Razor HD glass is as good and probably better than the Swaro non-HD. The Vortex eyepiece is also top notch. Throw in their warranty, and that just makes the decision that much easier. I'm not biased toward Vortex in any way, in fact I have more Swarovski stuff than Vortex.
