Sorry just seeing this. NSF provides their own index. The certification guarantees a label is what it says it is. I don't generally care about branding and let the certification + drug (creatine) do the talking. IIRC evidence points to monohydrate does the job well and no need to fuss with other things like micronized of proprietary creapure.
