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

Yes

The word "favorito" is identical in spelling, meaning, and grammar in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In Brazilian Portuguese, the vowels tend to be more open and the rhythm is more "musical" or "syllable-timed." In Continental Portuguese, vowels are often more closed or reduced (e.g., the unstressed "o" at the end may sound more like a very short, neutralized "u"), and the rhythm is more "stress-timed," making the speech sound more clipped.
