highly bling bling though
1. Please put the cas latency. It's only half the information we need to know if you don't provide it. In this case it's CL 36 and not that great. 36 * 2000/6200 = 11.6 ns first word larency, which is not great for expensive ram. Personally I would give up all the stupid RGB for better latency. I got 6000 MT/s CL 30 for $180 4 months ago, so this isn't a great deal.
2. It's not 6200 mHz. It's 6200 MT/s. If you're going to put the units, put the correct ones. I can forgive you because the listing on Amazon is wrong, but you probably should know the difference.
The sweet spot for DDR5 right now (cost/performance) is generally considered to be around 6000 MT/s with CL30. That results in a latency of 10 ns. A good deal on such a set should be around $170-180 for 32 gb.
If you go up in transfer rate, make sure that CL goes up respectively to keep latency around 10 ns. So if you get 6400 MT/s CL should be 32, and if you get 6800 MT/s CL should be 34 ideally.
Latency = CL * 2000/transfer rate.
Considering that the set in question is a slightly worse set than 6000 CL 30 (i.e. marginally higher transfer rate, but much higher CAS latency) it should be cheaper than $170 to be a good deal. Cost is sometimes higher because of cosmetic things like color and RGB. Just realize that if you buy this set you are paying probably $50 (~25%) for the RGB.

what is MT/s?
I looked up Corsair webpage but it shows "MHz"
https://www.corsair.com/us/en/Cat...M2X6200C3
Sounds like Mhz is just clock rate and mt/s is transfer rate and i get that Mhz/MTz is CL x200 (simply saying) ideally
so, disregarding price, below is correct 6400MHz / CL32 model right?

MT/s stands for megatransfers per second. The actual clock speed would be half that or 3000 MHz for 6000, or 3200 MHz for 6400, hense DDR or double data rate. DDR ram transfers data on the up swing and downswing of each clock cycle, which is why the transfers speed is double the clock speed. Old SD ram was 1:1 for clock speed and transfer speed. And it seems like even Corsair is propagating the misunderstanding of units for ram speeds.
A great video for DDR5 ram speeds was put up not even two weeks ago by LTT if you want more info or explanation on this subject.

Effectively, at the current state for DDR5 it doesn't help much to go above 6000 MT/s, especially for AMD, and you want to keep your latency to about 10 ns.
You can easily shop and compare ram kits on pcpartpicker. They let you sort kits based on transfer speed and first word latency, and then show you best price from all merchants.
