If looking for a strictly camp shoe and water crossings, I've found the Nothingz to be better than Crocs. They're lighter, have a more aggressive tread and you can get them with the closed toes. The closed toes suck for wearing around the house as they make my feet sweat like crazy but they're much better for camping.
Just weighed my size 13 Nothingz with closed toe. 13.5 oz
Very worn out pair of regular open toed Crocs without the backstrap size 12 15 oz.
That said I just ordered a pair of New Balance HI-REZ off STP to try as camp/water crossing shoes. My current water crossing system is a pair of glacier socks with the Nothingz over them, but I'd like something a little more secure on my foot.
Luke, what are you currently using for camp shoes?
