Which RAM module is better?

[black hawk]

The Crucial Pro RAM 32GB Kit (2x16GB) DDR4 3200MHz (or 3000MHz or 2666MHz) Desktop Memory CP2K16G4DFRA32A

or

Patriot Memory Viper Steel RGB Series DDR4 32GB (2 x 16GB) 3200MHz Kit, (PVSR432G320C8K)

I have a MSI B450M PROM2 motherboard. As per the ram company's website, these modules are compatible with the board. However, I can't get any worthwhile result in comparing the two. Timings are 22-22-22 for the crucial model, which I think would go against it.

Also, is it a fact that only selected modules support downclocking? After all, my motherboard doesn't support the fastest speeds.
