What’s going on with the English localization of rebirth?

So, I played rebirth and loved it. I played with Japanese audio and English text. I can speak Japanese, so I wanted to keep the original voicing because cloud’s VA goes hard.

Thing is, the English localization quite frequently would differ from the Japanese script, and not sure why. Characters were made to sound more sarcastic , and “cool”, and sometimes would say the opposite of the Japanese. Since I don’t have script in front of me, I can’t find an example. But I do know that the mega pinned post about the ending mentions the Spanish is better than the English.

Are the any other bilingual people that noticed differences when they played through? Even if not Japanese, I’m curious to talk about this.
