I have the Sigma 17-70 OS. I posted some sample pictures. As to your question, the Sigma has better macro and more zoom but the 18-55VR is no slouch when it comes to image quality. It is sharper corner to corner but the Sigma has better CA control. The 18-55VR has a little better distortion control. The Sigma is sharper at center and better built. I think if you get a good copy of the Sigma, the answer is yes. Luckily, these new Sigmas are coming out better. You have to test your copy as soon as you get it.
