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

Yes

The meaning, spelling, and grammatical function of "bons" (the masculine plural form of the adjective bom) are identical in both Brazilian and Continental Portuguese. The only difference is the pronunciation of the final "s". In Brazilian Portuguese, the "s" is typically pronounced as a voiceless alveolar fricative /s/ (similar to the "ss" in the English word "mass"). In Continental Portuguese, the "s" at the end of a word is pronounced as a voiceless postalveolar fricative /ʃ/ (similar to the "sh" in the English word "shoe").
