>>421388She doesn't pronounce all English words using katakana/romaji like most holos do. Good example is her recent English singing stream. In the first verse of "I want it that way" when she says "fire" instead of saying "ファイヤ", she pronounces it "Fi-YER" which is closer to the correct pronunciation. But then in the very next line she says "desire" using katakana like most nips would.
Considering how 99% of nips just default to using katakana for all English words, I'd say Suisei is better than most.
