JP Version is great and likable. Has a lot of range to convey all sides of her character. Haven't heard the english version, but no need to put one down. Plus all the localized text is still there. Either way, it's all pretty close to what she says in Japanese.
I'm not putting the JP version down, I just doubt that I would personally enjoy JP Futaba as much as the NA version. That's not a knock on the original VA at all. Plus, Erica Lindbeck is straight up one of my favorite VA's ever and I prefer the voice direction for her Futaba.
