I haven't touched the Hoffman, but the Kaufman fabric - I guess it is called the greyware? is just supremely fine-woven and has a wonderful feel. There is a watery-look to the batiks but they have a crispness at the light-dark color intersections, like oil and water, where some others I've looked at are blurry or smeary looking.
Oh forgot to say IMHO LOL!
