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

No.

While the spelling, grammar, and core meaning of "adorou" are identical in both dialects, there is a difference in typical usage. In Brazilian Portuguese, "adorar" is used very frequently and casually to express that someone "really liked" something (such as a movie, a meal, or a gift). In Continental Portuguese, while "adorar" is used, speakers more naturally and frequently rely on "gostar muito" or the characteristic "gostar imenso" to express the same level of casual enthusiasm.
