Good Kira wasn't religious enough to object to knockin' da boots, though. She was just all into the Bajoran spirituality and shit. And the Bad Kira was a sex kitten. Meeooow!

I'd choose the evil one too, though. You could probably get away with equally freaky sex play with both, but at least with the evil one you wouldn't have do deal with the constant "path of [your] pah" talk or have to go to the homeworld for blasted orb experiences.
