Rig has a great english voice.
Hayate, Bass, Jann Lee, Eliot, Mila and Christie's english voices are decent.
Kasumi, Brad Wong, Lisa, Bayman, Ryu, Gen Fu and Zack's english voices are meh and mostly not good.
Tina, Kokoro, Hitomi and Ayane's english voices are horribad. (though Tina's grew on me for whatever reason.)
Lei Fang's english voice.... MY EARS.
