Jesus, you're overly demanding. You wanted compatibility so I merely suggested two close sets with compatibility whether it was suitable for you or not. Nothing more, nothing less. But you make it sound like I'm trying to suggest you a whole library. And in the end, you still don't get the picture from how narrow-mindedly dense and demanding you are. You're more hopeless than I thought.
The set I linked has compatibility with Corsair and Razer, though it has translucent tops, you can easily do a custom quality DIY spray over it, since these keys are only sprayed, just like the ones on this drop. This is what I did, and it looks great. Whether you want to do that or not, up to you.
I don't know how long your "to this day" is, but the main reason you're having a hard time finding and why manufacturers neglect Razer and Corsair is because they have their LEDs north/top, so the front legends won't shine very well, especially if the switch housing isn't clear/transparent.
I've tried it on my Corsair, doesn't shine well, even though mine has Cherry's RGB/clear housing, even more so is that Corsair's keyboards uses a floating design so the light will leak out giving it less shine.
Tried it on my Razer, doesn't shine well either, even though they have larger LEDs and uses a closed design and not floating like Corsair. Front backlit legends will only work well with keyboards that have their LEDs south/bottom. The rest, I'll let you figure that out.
If you think the photos in the description page shows backlighting well, then its not like that in actual environment conditions unless you're in a dim room to dark room. Not deterring you here, just merely letting you know.
As you desire them so much, as said, Good Luck.
