Myself, I have been using a Kinesis RGB Edge with the "lift-kit" for about a month. Have never been a perfect, trained touch-typist - so there has been a learning curve, but it is worth it. My wrists feel so much better, and I am almost back to full speed. (Previously, I would just use laptop KB's). The only complaints... Not from me, but when I am on web meetings, I have to be on mute, because everyone finds the KB…
The customization of both the RGB and the keys themselves as well as the ergonomics have been well worth it. I use a USB switch and use the keyboard for both Windows gaming and development on Mac.
One quirk of my typing style is that I use my right index finger for the space bar, so my left space bar effectively went unused when typing. I rebound the left space bar to the Command Key on my Mac profile so I can use my thumb for it like I would on a Mac keyboard.
I use it for gaming too. Sometimes I move the right side completely out of the way so I'm just using the left and my mouse.
I'm not saying these are all features exclusive to this particular keyboard. But a split keyboard was a great investment that I'd recommend.
