We have both of those toys.
The ball didn't last long at all. The squeaker came out & now Princess wont touch it. I don't recommend it personally, if you have a chewer.
However, for a chewer or any other pup, I highly recommend the Cuz.
Princess looooves this thing & I do, too. lol. It is so thick, she's tried a few times to get the squeaker out & has barely left any marks on the ball. Since it has the legs it's easy to take out of her mouth & even tug a little with it. The legs also make it bounce funny when you throw it & it can go in any direction which she loves, too. It has a very loud squeaker but Princess can't squeak it too much on her own. And when I do it she about jumps out of her skin with excitement!
I ordered mine from YTer mimimomo @ toplinepet.com.
