If it was me doing this, I think I would go with the top two choices for sure, plus the all white original button. Then pick one of the two buttons above (I prefer the brown one, but whatever). If you feel like you need to go with #4 (all white on one side that matches the original button, and the KQ on the other side), that's fine, but there's a lot of KQ going on already, and the fact that the one side matches the original exactly doesn't really do anything for me. I like the button in a vacuum, but considering the original exists, I don't like it quite as much.
