I love Christie's voice the most. There's also several others I like, all of the ones you mentioned are on that list.. Well, except for Mila.. For some reason, I can't stand her English voice. >.>
@Chapstick I agree. The English voices are way better than people give them credit for. I never really gave English voices a chance, because I'd heard from other people how bad it was. It turned out, after giving it a chance, it's not half-bad.. :P The biggest problem is the lip-syncing, which is made for Japanese voices..
English voices IMO:
Good Voices:
Bass, Tina, Mila, Leon, Sarah, Jacky(lel), Honoka(not just saying this because I used to know her back on Newgrounds >.>), and that's all I can fit in.
Leifang's English voice while fighting sounds like Numbah 5 out of KND xD . Yeah, the only English voice I don't like is probably Leifang. Dimensions' English dub was awful though
Ever since dimensions i've refused to play with english voice acting. The voices seemed really out of place, and some of them just plain didn't match the characters (Kasumiα sounded older than Kasumi).
