Hola,
I’m a native Spanish speaker from Spain (I live in the U.S., spoke English all my life with a native English speaking father and my English could be better than my Spanish). Since I am Spanish, we use vosotros. While I heard people in the U.S. learn “ustedes comen”, I would say “vosotros coméis”.
Half of the US used to be Mexico, so US Spanish is mostly Mexican Spanish. We don’t use vosotros. My high school Spanish teacher (yes, I took it because it was easy) would always skip conjugations of vosotros entirely.
I don’t think I’ve ever heard anyone use vosotros here. We understand it, but it’s very uncommon. Univisión, Telemundo, Estrella, TeleXitos all mostly use Mexican Spanish. Same goes for the radio.
