I checked out Sanjay's articles, but he hasn't mentioned or tested these particular bulbs. I don't know if you could generalize from one to the other -- but maybe they all come from the same factory in China.

In my case i find that color of the coral (SPS) is as much dependent on the water quality and amount of flow as it is depends on the light. I use to have a lot more light in my earlier tank (400W 20K) then i do now but with better water quality (less bio load, amino acids,bacteria addition and Bare Botom) and more flow i am able to keep SPS with better colors.
