Msi Pro Z690-A Wifi DDR5 motherboard

i7 13700K

I am looking to get either around 32GB (2 stick) of DDR5 preferably around 6000 or 6200 MHz. I read that sk-hynix die is better DDR5 and basically to avoid Samsung. Currently I am looking at following options. I would really appreciate if someone knows why there is so much discrepancy amongst following and their prices. Also I can't get any info if any of the following have sky-hynix die:

G.Skill Trident Z5 32GB (2x16GB) 6000MHz DDR5 (Same as above, don't know why it's way more expensive!)

Last one is which I am thinking of buying but I find it weird that despite it being 6200MHz and being low latency it is cheaper than most.
