Without getting too technical, the API and the Hagen ammonia tests are
not the same, and actually measure slightly differently. At work, I
sold Hagen, but I smuggled in API ammonia testers to use when I was in
a hurry (customer water tests).

Which is best for you depends on your pH, but I wouldn't worry as
ammonia tests are the least used once the tank is established. Which
pH tester also depends on your pH, and I'm going blind from trying to
figure out API's gH test, and someone show me an accurate NO3 test....
*grumble, venting pent up reagent frustrations*.

API's gH test:
Ok, so it's not just me who has trouble
distinguishing yellow from pale green?

I've taken to looking down the tube instead of through it. For some
tests (ie: titration) this seems to work a bit better.

Another trick, use half the water (2.5ml). Now each drop represents
2dgH. Saves reagent when your water is liquid rock (and who cares if
it's 36 or 37dgH ;~).
