The tightness of the weave and the weight of the threads can be different. I used to see a lot more coarsely woven wide width backs than I do nowadays, so my Jinny Beyer back felt much different than the regular width yardage.
I sort all fabric on a piece by piece basis with no regard to brand by feel. I've had high priced name brands from LQS turn into a crummy rag after washing, I've had lower brands that behaved superbly despite their humble beginnings.
