The Glock 17 is a relatively lightweight pistol with a polymer frame. It is striker-fired. The Glock should run you between $450-$550.
The Sig P226 has an aluminum frame, rather than a polymer frame, and the slide on the Sig is quite a bit thicker, making it a noticeably heavier pistol. Also, the Sig has a hammer and is a hammer-fired gun. The Sig has the capability of being fired both in single-action and double-action modes. The Sig should run you between $800-$1000.
Like others have said, because these guns are so different, it depends on what you think after shooting both.
Aside from what has been mentioned above(100% accurate BTW), the single biggest difference is the angle of the grip in relation to the slide. Glocks point high for me while Sigs point naturally. Sure, you can adjust and become competent with either, but I always go for the gun that feels the best while shooting. The difference in inherent accuracy of these guns is negligible.
