I have Aquarium Pharm, Tetra, and Azoo KH test kits.
They read my tank water as follows:
Tetra - 6 KH *
Aquarium Pharm - 8 KH *
Azoo - 5 KH *
I have always used the Tetra test. But, as that bottle is starting to run low, I tried out the other two KH tests (they came as part of a 'deluxe' test kit).
Any experience/recommendations? I'm a bit disappointed with these results. Accuracy is pretty important when dosing CO2 :x .

*tested 3 times each - same results
