Euro knits (specifically Swafing) vs Art Gallery knits Sewing Machines Parts and Sales in Los Angeles

For those who have worked with both, I’m debating between knits from Swafing or knits from Art Gallery; so how do they differ in quality, colour fastness, etc? Which do you prefer? I’m in Canada so they’re both pretty pricey; I want to make sure I’m getting the best bang for my buck.

How do they compare with say Riley Blake knits?
