Again, The GX chains that are referenced in that article are for Eagle 12 speed, ie, NOT TRANSMISSION.
Again, "With Transmission, I'm guessing the best value service life will be from the GX chain" Emphasis on the word TRANSMISSION!!!
Eagle GX 12 speed is the old stuff.
Transmission GX is the new stuff, with the flattop chains.
You do you. I'm going to spend more time riding and less time fixing and replacing chains. X0 or XX transmission for me.
