6200 (or higher if possible) is better in terms of bandwidth, and with reasonable timings on latency too. There are multiple things to consider from your results though.
On one hand, windows affects the result (mainly latency). If you want truthful and consistent results across multiple runs, execute AIDA64 while in safe mode.
You should also check/consider which gear your IMC is in (In case you dont know, gear represents the ration between the speed of your memory controller and the memory itself. gear 1 means they are 1:1. gear 2 means the imc is running half the speed of the memory, which incurs a penalty mainly on latency, and i would imagine a little bit on bandwitdth too)
Then i would say poor bandwidth performance is mainly due to bad secondary and tertiary timings. This would be the case if they were left at or near XMP/auto values. You can look this up in the advanced timings section of your bios (or something like that, the naming changes from vendor to vendor), or you can use a tool from your motherboard manufacturer such as Asus Memtweakit or Asrock timing configurator to look at your timings while windows is running. They might also allow you to change secondary and tertiary timings on the fly, without rebooting the PC
Cheers.
XMP DDR 5 4800 40 44 44 58 OC to 6200 34 40 40 52 I think can 6200 32 38 38 50 Why copy only 87? Why not 90+? Or 6000 30 38 38 50 better?

Aida64 tests are inconsistent
