32GB CL18 vs 16GB CL16: Capacity wins for most people

Get the 32GB kit with CL18 over the 16GB CL16 kit. The latency difference between CL16 and CL18 is real but tiny — you won’t notice it in games or daily use. What you will notice is running out of memory because 16GB isn’t enough for modern games and multitasking. Unless you’re chasing benchmark records, take the capacity.
