EDITOR'S OPINIONLani was good at making Omochao sound annoying, but the way she delivered her lines felt awkward. She did a bit better in Sonic Heroes, but Omochao's role was pretty decreased in that game. Liza was all right. Nothing too special, but not horrible. Rebecca wasn't really that great and my least favorite, but Omochao didn't have much to say in that game.
That leaves my favorite, Laura Bailey! She managed to fit Omochao's personality and actually make him likable and funny. Plus, she got some good lines to work with.
