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

Yes

The spelling, meaning, and grammatical usage of "surpreendente" are identical in both Brazilian and Continental Portuguese. The only difference is in pronunciation. Brazilian Portuguese is generally more syllable-timed, with more open and clearly articulated vowels. In contrast, Continental Portuguese is more stress-timed, meaning unstressed vowels undergo significant reduction, often becoming nearly inaudible or much more "closed," which gives the word a much more clipped sound.
