In a few cases, like Simple, Simple Ultra, and Betterdry, I've only worn the printed versions but they are described as the same diaper without the print, so I think I can grade them as well. Anything rated 3 or better, I'd happily pay for at the prices I've typically seen them. Lower, and I'd need a sale or particular conditions under which I might consider them okay. I didn't include diapers that are no longer in production.
