I find them both to be excellent, though in different ways. The Northshores wick very well and pull fluid away from your skin and hold a LOT of pee. I can normally make use of nearly the entire diaper before having to change. They seem to be sized similarly to most others. They do start out stiff, but if you fold them to activate them, as directed, they soften up some. The 24/7s, on the other hand, are sized a little bigger, so that a Medium 24/7 is somewhere between most other mediums and larges. They are comfortable and seem to have a higher SAP content, making them absorb quicker and more able to handle a sudden flood. They don't wick as well, so they are prone to clumping in front, and don't distribute the liquid to the back of the diaper as well. If I had to pick one, it would be the NS, though I use both (as well as others) depending on my needs, mood, and how my bladder is acting at any given moment. One other thing - if I know I'm going to be sitting for long periods, I lean toward something with a higher SAP content (24/7s, Better Dry, etc) so if I flood while sitting, it will absorb quicker and reduce the chance of leaking out the sides. Hope this helps!
