Having never owned either of the two rifles you mention, I would have to go with customer service, customer satisfaction, over all quality and finally price. I personally would stick with a Thompson Center Product, that being the Omega. I would also get the rifle in Stainless Steel. Almost any Omega owner you talk to tells you about excellent quality, excellent accuracy, easy cleaning and just being overall pleased with the rifle. While I am sure the Knight is a great rifle, the Omega started this whole break open thing. It is a known performer.

The White Rifles are simply another brand of rifle out there. They are a .504 caliber and are best known as conical shooters. What many of the White owners, including myself are discovering is, these rifles will shoot anything you want to stuff down them and the overall quality of the rifle is excellent. They are not break open in design.
