Gumshoe becomes slightly Flanderized, Apollo gets better, so I voted for Polly.
But also I feel like Apollo is a bit of a grab bag of a character. Because he's kind of a nothing character in his own game, he's basically able to be whoever the writers want him to be in DD and SoJ. They do interesting stuff with him, but it's also a bit wacky. If there's an AA7, I'm sure the writers can ret-con in another interesting fact about his backstory.
