I've been keeping up with this thread a lot and thinking about it a lot and I've pretty much come down to a couple big points. Daisy's thematic resonance is just way the hell stronger, it's not even close. They built parts of the game around that version of the character and made no adjustments to those thematic elements when the Emperor got tagged in. It's a damn shame. On the other hand I do think prior to the reveal, the Emperor works better as a narrative device. It would've been nice to see more of a middle-ground with a Daisy that isn't so obviously tempting you to do evil, who doesn't get revealed to be who the Emperor is, so that we don't end up wondering why we even bothered to make the Guardian in character creation to begin with.
