I have no idea why so many people joined this drop. It makes no sense. You can buy exactly same keycap set from maxkeyboards for only 20$. I think this is just a mass not a drop :)
maverichYou can't really compare Max with Originative. Max keycaps are just alright. They are not bad but they aren't amazing either. While Originative is highly sought after, especially their premium ones.
The $20 ones you mention looks to be ABS. These are doubleshot PBT. Company names aside, you cannot compare ABS to PBT. There's no contest.
kyznThere isn't a contest, you're right. It's all down to preference. A majority of keysets made by SP are ABS, including the SA and most DSA sets. As far as I know, every GMK set is ABS...
