Classico(large), the plastic backing seems the same, but it's like they spread the absorbant stuff a little more and also there's less of it, the tapes tear(rip) away from the backing with less effort than you'd expect, leaking is a lot easier, without the extra fluff in the front, pee comes up over my hips and leaks out, it still sort of neutralizes the urine smell so that's good but it's a definite step down, I mean no matter what position you're in you're going to leak if you flood them, the last case I bought didn't have that dysfunction. Sorry I'm only a recreational user btw, so idk how or if 24/7 people can tell the difference.
