Once I move to one of the newer platforms (probably next Spring), this is what I'll end up getting. Microcenter tends to stock it and while Corsair stuff is rarely the performance leader, their stuff tends to be stable and well supported.

Why 6200 have better timings than 6000 and 6400?

This depends on the manufacturer and the used chips (is it Hynix, Samsung, or whatever else) or the so-called "die". Overall you can find, for example, the 6000 MHz with CL40, CL36 like the reviewed ones, and even CL30 for some G.Skill kits. It's not strictly restricted (I mean the timings) for each frequency.

actually these are great sticks of ram they're locally (Silicon Valley) the market leader and their price is well below the G.Skill @ same timings for both plain and argb sticks (locally) i finally ordered my AM5 mobo MSI PRO B650M-A WiFi Pro ($219.00US) and i ordered a set of these black rgb sticks to go with

As already said: depends on manuf. of modules and chips, but I think what you meant as well: when it comes to new ddr RAM, I also feel a bit unsure on how to compare speed with my actual sticks. As a very basic rule and for a first comparison I do it like this: Latency is the number, or better, is expressed in "the number of clock cycles at a certain frequency". Which means, if frequency doubles each clock cycle needs half the time to complete. For example, a latency of 36 at 6000Mhz is equal in absolut time measured in nanoseconds to a latency of 18 at 3000Mhz. Certainly many RAM pros out there who can explain it far better, but it´s the way how I do it.
