Are 360-style spoutless cups actually better for kids?

This is the most contested question in the category. Verified-purchase reviewers love the spill-proofing, but a high-trust thread on r/beyondthebump cites feeding-therapist concerns that 360 cups encourage chin-tilting and may not develop the same lip and tongue patterns as open-cup or straw drinking. Many specialist-community parents use them for travel but pair them with straw cups at home.
