memory with samsung B-Die is the easiest to work with and usually overclocks pretty well. the RGB versions have been problematic. I think they have resolved it but I would avoid it myself.
checking against QVL is a good idea. You really need the best balance of frequency and latency. 4000c19 memory is expensive but doesn’t really get you anything more than a 3600 kit
Gskill Trident Z 3200c14 is good and can be run at 3466c14 if you get a good kit
the Gskill 3466 is also good.
the 3600c16 is also great but you need the 16-16-16 version, not the 16-18-18 which is Hynix dies
