You can buy retail kits that are DDR5-6000 with 30-39-39-96 timings and easily get them to 28-36-36-50 without much trouble. Don't see the point in paying more to get the same results. The benefits of buying a higher binned kit is that eventually you may be able to run it at those speeds.
The cut-off for Ryzen 7000 CPUs is 6000-6600 MT/s for memory 1:1 Ratio. My opinion on the subject just like the previous AMD (DDR4) generation, Go for the maximum the CPU IMC can run in a 1:1 ratio configuration and the lowest timings possible. Just for an example, 7200 MT/s in 2:1 trails behind 21%~ in the benchmarks I've run vs 6000 MT/s 1:1 (low graphics). However once you are GPU bound, like playing at 4K max settings, they are within margin of error and to be frank, it kinda doesn't matter what you have. Though technically, the 7200 MT/s kit is worse in synthetic benchmarks and 1% lows (some games).
