Anyways, Stewie. Hands down. Maggie's just a typical toddler, but Stewie seems to be an utterly snobbish 19th Century Gentleman accidentally put into a baby's body.
Maggie however isn't typical. She appears to be innocent but she is intelligent. It is obvious however, that Stewie is intelligent and evil but no one around him recognizes that.
i like Stewies character. mainly because his a hell lot funnier. and maggie is just a baby and can barely speak and Stewi can talk.. plus the things that Stewie does is really funny in a very weird way..
I think we can't compare the babies, because Stewie appear a lot of more times in Family Guy. Instead Maggie most part of the episodes just appear in Marge hands LOOOL
Stewie, first of all, he is funny, and another thing, he can make fun of so many people in the show and it cracks me up. But Maggie does anything and people barely notice. She also has acrobatic skills. I still like Stewie!
