I haven't used any Attends products in years, though my memory of them was that they were a (slight) step above the Depend diapers of the day. From what I hear, they may be significantly better than the current Depend. I've tried the Dignity PM more recently and was not impressed. In fact, I still have some and am considering throwing them out. They don't hold much and, despite having a cloth-like outer cover, are crinkly as all get out. Seriously, these things are noisy.
I know that "good" is a highly relative term, but I wouldn't consider either of these to be in the same class as any of the better diapers now available online, or even mid-level diapers like the Tena Super.
