Jennette. I think she gets a lot more range on the show in terms of acting, for one. Her mannerisms and even her voice (though subtly) changes when she plays Sam. Miranda isn't offered that type of range, because Carly (from what I've seen of Miranda's personality) is basically a more kooky version of Miranda herself. Miranda also has trouble transitioning from character to character. I noticed that her performance was particularly weak in iPilot, as though she was so used to playing Megan that she found it difficult to play someone basically the total opposite of her. Likewise, when she played Megan again in Merry Christmas Drake and Josh, her performance wasn't as convincing as usual, as though she no longer knew how to play Megan and was, at that point, stuck on Carly.

Jennette is also the better singer. Her voice is stronger and better, and doesn't need much editing (if any at all).
