[SOLVED] 64GB ram, CL16 3200 or CL18 3600 MHZ?

Solution
The 3200 would be better since it's cheaper, but also because I don't believe you can get faster than 3200MT/s in dual rank configurations to work with Ryzen 3000.
hands down, the 3200mhz kit.

People tend to way over hype 3600mhz for 3rd Gen Ryzen. In reality, it isn't that much of a performance upgrade. Gamers Nexus did a great in-depth video regarding memory speeds for Ryzen and 3200Mhz is really still a great speed for everything. 3600Mhz is barely even a 10% performance upgrade. (Assuming identical timings for 3200 and 3600 kits.)

Not to mention, the 3600Mhz kit you linked is CL18 vs the 3200 CL16 kit you also linked. CL18 is effectively the same speed at 3600 as is CL16 at 3200Mhz. So you are literally wasting your money if you go with the 3600mhz kit.
