Which editions? The Iberian Spanish ones are not that different in tone/speech to the original English ones.

Yes, Iberian spanish. The issue is that I'm from Latam, so the slang used in Iberian spanish, and some conjugations still sound foreign to me. In english, King's words flow better, the intent and the idea are much clearer, and since I've been much more exposed to American culture than Iberian culture, it feels much more familiar.
