13.75ns CL in Dual Rank vs 12.5ns CL in Single Rank (2Rx8 vs 1Rx8)

Question

Which would be a better choice for gaming/video editing in a 32GB SODIMM kit (2x16GB) on HP Victus running Ryzen 5600H:

A higher CAS latency on a dual rank (& dual channel) memory or a lower CAS latency on a single rank (also dual channel) memory?

Are there any benchmarks that indicate precisely the ups and downs of dual rank memory?

Thanks!
