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”.
I learned spanish in colombia. I learned the vos conjugation (it’s the best since it’s so easy to conjugate) but never learned vosotros because they don’t really use it where I live.
Soy de los EEUU pero vivo en Medellin.
¡Qué interesante! Vivo en los EEUU como ya dije, jeje
