Katie went first on the show, so fanfic writers tend to boot Sadie first for the sake of being different, or merely because they think Katie's hotter. This happens so often that it's become a convention in its own right. Add to this the fact that Sadie's widely considered to be the wiser of the two (although that may not be saying a great deal) and has very different physical properties from most of the other girls, and it's clear that having Katie go first affords more opportunities if you're looking to do something unconventional.

On the other hand, with the clones on opposite teams, keeping them both around for a while provides its own set of opportunities to do something out of the ordinary. But whatever you do, please don't boot them both early. That's just too much wasted potential.
