I have used both quite a bit, and have decided that I don't really like the Hobbs 80/20. Part of that might be that I buy the W&N on a roll, so there are very few wrinkles to deal with. the Hobbs I have bought in packages where it gets all creased and stretche out, and have to put in a dryer for a while. What I really just don't like is the feel of poly on my hands. Just don't like to touch it. In the finished quilt, it's perfectly fine though.
