g.skill trident z5

Hi all! I'm looking at which RAM to go for and it's between these two. My question is - why are the comparable parts (6000MHz, CL30/32, 2x32GB) so different in terms of the final timing and what does this actually mean/impact? Corsair - 40-40-40-77 (CL30 - they don't offer this in CL32)...
