New 64GB kit advice for AMD

[arconz]

Which of the following 64GB kits (2x32) would be best for Ryzen 3900 series? I will actually be buying 4900 series (or whatever they end up calling it) in a couple of months but I assume it will be using the same DDR4?

Gigabyte Designare DDR4-3200MHz CL16-18-18-38
Trident Z Neo DDR4-3600MHz CL18-22-22-42

Primary use is for an editing & 3D simulation workstation, occasional gaming but not much.

The Gigabyte is actually NZ$80 (44 euro) more expensive... not a deciding factor considering the cost of the rig.

One thing I noticed is that it seems to be very difficult to find higher capacity dimms like 32 GB that don't have slow latency timings... not sure if that's a limitation of ram design or something...
