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

Yes

The word "preferimos" is identical in meaning, spelling, and grammar in both Brazilian and Continental Portuguese. The only difference lies in pronunciation.

In Brazilian Portuguese, the vowels are generally more open and clearly articulated. In Continental Portuguese, unstressed vowels are often "reduced" or shortened, meaning the "e" sounds might be much more subtle, and the final "s" is typically pronounced as a "sh" sound (palatalization). Therefore, to a Brazilian, the Portuguese pronunciation may sound like "pre-fe-ri-mush."
