Is the word nós the same in Brazilian and European Portuguese?

No

While the meaning, spelling, and pronunciation of "nós" are the same in both dialects, there is a significant difference in typical usage. In Brazil, the pronoun "nós" is frequently replaced in informal, everyday conversation by the expression "a gente" (which uses 3rd-person singular verbs). "Nós" is typically reserved for more formal, written, or emphatic contexts. In Portugal, "nós" remains the standard, default pronoun used in both formal and informal speech.
