It is thicker, stiffer, more industrial feeling. It reminds me of heavy rain jacket material. It's probably a little easier to sew with than PUL because it's not as flimsy or stretchy, but IMO it's not very attractive. It's hard to explain without seeing it, but on PUL, there is a nice fabric side and the back side is laminated. You sew with the laminated side toward the baby. With procare, the plasticy side (shown on their web page) is the nice side and the back is UGLY. It seems weird to have the fabric side facing the wetness, but you either do that or have an ugly outer. Because of it's unattractiveness and industrial feeling, I haven't used it much for diapers. It does soften some with laundering and makes great wet bags. It would also work well as a hidden layer under a cute outer, but would be bulkier than PUL.
I think the Wazoodle site says you can only expect 20 home launderings from standard PUL whereas their PUL can withstand 100 washes and procare can withstand 1000. I don't believe that statement to be true. People use PUL for many months/years, on more than one child, etc. while laundering several times/week. PUL lasts much longer than 20 washes or no one would waste their time with it.
Like most things with sewing and using CDs, it's largely a matter of preference, but I wouldn't recommend procare over PUL unless you're really having trouble sewing with PUL or you're sewing for charity, such as an orphanage where form is far more important than function and they need to withstand a lot of heavy duty laundering.
