I would take 3466mhz C16 over 3600mhz C18. I found that with my Trident Z 3866mhz kit that 3600mhz C16 is better in most benchmarks than 3866mhz C18 and better in a lot of benchmarks than 3866mhz C17. I did a lot of tweaking and testing over a week to find that the sweet spot for my kit is 3600mhz@C16. I tested 3400mhz@C14/C15, 3600mhz@C16/C17 and 3866mhz @C17/C18. I am currently set at 3866mhz C17 but that's only because I can't work up the courage to go back in my boards damn awful bios.

haha! yeah memory tuning on the Aorus Pro board is an unpleasant experience and that's being polite.

I gave up and just run 16/16/16/36 3600mhz with secondaries on auto. It's just not worth it.

That's a interesting tool. That shows very little difference between 3200mhz C14 (8.75 ns) and 3866mhz C17 (8.79461976 ns) yet 3600mhz C16 is 8.88888888 ns which goes against most of the testing I have done. Playing around with memory timings and speeds is mind boggling!!
