What are the advantages of circulating oil design vs deCarbon design shocks?

Popular and expensive shocks like CCDB and Vivid use a circulating oil design, and it is used as a selling point.

In addition to port, needle valves, and shim flexion, in a circulating oil design the speed of the oil circulating will be independent of the frequency but vary with the magnitude of shock compressions.

As for deCarbon design, I like to think of this as oil being "static" and providing friction for damping, and the piston and IFP moving through this medium. The speed of the "stir up"/friction/flow in the oil will vary with both frequency and magnitude of the compression.


One would believe the independence of the shock frequency would make for less effect of the shim-damper in the circulating oil design.

From a understanding of the physics involved, apart from the advantages of better heat dissipation (not a problem in our local subarctic climate), why does the ciculating oil design give any better control over the damping than the deCarbon design?
