I originally had a 2x16GB TeamGroup T-Force DDR5-6000 CL30 kit, which I mistakenly thought was only 4800 MT/s. I later bought a 2x16GB Corsair Vengeance DDR5-6000 CL32 kit and tried combining it with the T-Force memory to reach 64GB. That caused blue screens and other stability problems. I also bought another Corsair kit after mistakenly assuming the first one was faulty, and it turned out the original Corsair kit was defective and needed to be exchanged. Now I have three 2x16GB kits, with two Corsair kits that should match and one T-Force kit with slightly different timings. I need 64GB for DCS and may eventually play in VR. Should I return or sell some of this memory, run a mixed Corsair/T-Force setup, or sell the T-Force kit and keep the Corsair memory?

The fact that the Corsair kit felt faster does not necessarily mean it is performing better. Capacity, subtimings, BIOS training, and stability can all change how a system feels. Prioritize a stable matched kit over combining several kits, and return or sell the extras rather than trying to force all of them to run together.
Since you already have multiple kits, you can test them separately. Try both Corsair kits together with their EXPO/XMP profile, then test the T-Force kit by itself using its rated profile. Compare stability and game frametimes, but mixing kits—even at the same advertised speed—can still cause crashes or require lower settings.
I would avoid mixing the T-Force and Corsair kits if stability matters. If the T-Force kit is the better-binned 6000 CL30 kit, you could sell the Corsair memory and keep it, but that only makes sense if 32GB is enough. Since DCS already benefits from more memory and VR may increase that demand, a matched 2x32GB kit is the safer upgrade.
I do need 64GB for DCS, and I expect the VR version to be even more demanding. I was worried that going back to 32GB would just create another limitation.
