bought these keycaps on massdrop when they were doing the drop, actually. hopefully none of my keys are missing like they were with the vortex set
I also joined the drop and bought 2 sets for my Ducky Shine 3/4 k-boards.
Are these Side printed keycaps better than Vortex?
Sorry, I don't know, I don't own a Vortex keycaps set and all I can say that I don't like white and black keycaps/sets very much.
