Nana has possibly the best English vocals out of the Japanese-English banks. It's certianly the most HQ and since her bank was intentionally "engrished" it meant that there was little tone variation between her English and Japanese, and I can assure you it is not Miku level cringe worthy.

As for voice providers level of English all I have to say is look at Luka who's voice provider was good at English.
