Thoughts on Simplot Best Fertilizers

I was wondering what y'alls thoughts were on the Simplot Best brand fertilizers. I am specifically looking at Nitra King 21-2-4 (I need P and K per soil test). It has Iron Oxysulfate in it which from my research is mostly Iron Oxide and therefore pointless in my 7.8 pH soil. It also has Ammonium Sulfate Nitrate which seems to be two AN molecules bonded to a single AS with added AS. I am not sure about the benefits of Ammonium Sulfate Nitrate over just Ammonium Sulfate.

Edit: I spoon feed my lawn so I am not looking for any type of time release.
