I'm the coolest girl you'll ever meet
Im really struggling to see the merit of the mixed set over cb. Without kings shield being able to switch moves does almost nothing as you are slow and frail enough to be easily ohkod, only helping you prevent set up, at the cost of making you so much easier to play around. The increased power with shadow sneak is helpful, the ability to just click head smash and have the opponent have almost no possible switch ins is helpful. At the very least cb is as good as mixed in my opinion.
