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”.
Same for me. I’m currently taking an adult learners Spanish class and the text book has vosotros listed but our teacher told us not to worry about it. I live near the Mexican border so the class focuses on Mexican Spanish.
