The two above each contain stuff I already have tests for, but neither contain both Calcium and Alkalinity.
Then there are tests for Magnesium, Iodine, Silica, Residual Ozone and Oxygen, Carbonate Borate, Strontium...? WOW!
I used the Red Sea kits for years, but am in the process of a complete switch to API. The API kits are easier to use and read. You have to buy Calcium and Alkalinity individually, they generally don't come in the kits. There is a school of thought that says these kits are only needed on reef tanks, which is ridiculous in my opinion. I think this originates from the LFS trying to convince the average Joe that saltwater isn't much different than freshwater.
As far as product, you could make an argument that BIonic is the best. I use the Kent products because I am comfortable with them after 10 years or longer using them. The BIonic product is really about the same thing, with one part being Calcium Chloride and the other part being carbonate and bicarbonate buffers.
