I don't own a cube with Cubesmith half bright, but I've seen one from my friends before and it definitely became the most appealing sticker set I've ever seen until now. It gives good recognition without becoming a little too far off from the standard color scheme.
I'm planning to get Cubesmith White Cube Half-Brights for my Lubix Fusion, but so far I haven't used any other stickers than the ones that came with my cubes.
