I recommended API as it's an easy all round solution and I think the levels are not that far off as I have compared them numerous times to Salifert kits for ammonia and nitrite.
But, I do use Saliferts most for my ammonia and nitrite. I think the colour chart is easier to read as well. It's just that a full set of ammonia, nitrate, nitrite and maybe PH can cost near in £50. That may put the more general hobbyist off. Better they use a slightly less accurate kit than none at all.
However, for PH, you are better off buying a PH pen and a packet of buffer solution to calibrate it. Not complicated or expensive at all and gives a bang on reading as long as it's calibrated properly.
