The SRAM flat top chain works just fine with both Campy and Shimano GRX cranks and Campy 12 cassettes. The combination is incredibly quiet. I tried a Shimano 12 chain and found that it didn't work great with a SRAM AXS cassette. I had shifting problems in the 13-14-15 range. If someone wanted to create a mixed drivetrain with a Shimano 12 cassette, it would work fine.
