I'm confused, what else do you want the seller to provide? There is the actuation and bottom out rate, and all the materials used to create the switch as well as the fact that it is linear. Do you want them to specifically spell out that "X has never been done before!" Because validating that claim would be silly and evidenced by the specification list.
Whether it's better or worse, especially with switches, is completely and utterly subjective. No one can tell you what switches you will or won't like. That's crazy. If you like heavy, linear switches, and Gateron Blacks just aren't enough, and are in the market for some, here you go. I don't understand your logic here. Why should anyone sell you on a switch you may or may not like? Is this your first dive into custom keyboards?
These have very different specs than other Gaterons, so they aren't imitating anything, and they come factory lubed, which could potentially save me time (if they did a reasonable job). If you're not sure what kind of switches you like, there are loads of testing kits out there so you can try different switches with cherry keycaps on them or put your own on, or plug them into your keyboard and try them out.
This is not here to be sold to someone that doesn't know what they want.
