Sippy cup recommendations

We bought my LO the munchkin 360 but he doesn’t seem to drink any out of it and mostly all of the water spills for some reason. He seems to do fine on this philips avent sippy cup but I’m just wondering what are some good sippy cups to be able to make baby drink water to avoid constipation.
