We use the Re-Play sippy cups, they are amazingly durable and spill proof. I actually take the little rubber stopper, which makes them extra spill proof, out because it just seemed to hard for my kids to drink out of it. We used to use the 360 cups and I loved them. However, my son started chewing through the rubber piece on the top of them. I was over replacing them constantly. Lol For water we have contigo water bottles, but like someone else said, I don’t like putting anything but water in them.
