Major Stars ABS Backlit Shine-Through Keycap Set

So I bought two of these, I love them to bits, but i can't find anything that's on par, Some questions I had, people claim ABS is cheaper than PBT, but i've bought my fair share of PBT and PBT doubleshots, they're all rougher, these are definitely softer, sure GMK is softest but for the life of me they'll never have shinethrough / backlit options: Why are these softer than PBT ? Are there any other abs doubleshots you'd recommend? Why aren't abs doubleshots as common ? why does the majority of the community prefer rougher pbt keycaps or non lit GMKs?

pretty sure it says abs
