I genuinely think the localization's better to play just because of the reduced encounter rate and the better experience gain, it makes the game less repetitive and an overall better experience. The dialogue and miscellaneous changes that they did in the US version on the other hand as mentioned by many people is definitely some of the worst I've ever seen. One of the biggest things this affects is the skill/demon names and not knowing what the fuck anything is because of it, but the dialogue had a kind of "so bad it's good" quality to it to the point where it kept me entertained and wondering what absurd thing I was gonna hear out of a demons mouth next. Also the soundtrack slaps!
