Which of These RAM Kits Would be Best Paired with a 3900X?

[Lazmarr]

I'm looking at upgrading my PC to a 3900X and will need to purcahse some RAM.

I have heard that Ryzen 3rd gen favours high clockspeeds and low latency.

I've been looking at the G.Skill Trident Z RGB for styling, and can purchase the following RAM, but am not sure which would be best.

 

G.Skill Trident Z RGB 32GB (16GB x 2) 3200MHz CL14-14-14-34 - F4-3200C14D-32GTZR - £250

G.Skill Trident Z RGB 32GB (16GB x 2) 3200MHz CL15-15-15-35 - F4-3200C15D-32GTZR - £218

G.Skill Trident Z RGB 32GB (16GB x 2) 3600MHz CL16-19-19-39 - F4-3600C16D-32GTZRC - £180

 

I've had trouble locating sellers of the G.Skill RAM in the UK, but these are what I have found so far.

Ideally I'd like to overclock the RAM to 3600MHz, is the CL14 kit worth the price difference?

 

Which of these would is best paired with the 3900X, and which would you suggest is the better to go for?

Those 3200 speed kits appear to be b-die by the timings.  The 14 kit is better binned and has a stronger chance of reaching 3600.  Folks seem to get them up that high pretty regularly.  If you can find a 3600CL15 kit that will be b-die too, but I haven't that kit available lately.
