Coolant system design is an engineering problem, not a marketing gimmick.

The key issue is temp differential between inlet and outlet. So if you put 180 degree hot water into one side of the radiator how cold is it when it comes out. The bigger the delta then the better the cooling system.

That is really the only thing that matters, everything else works to make the differential happen. Water velocity, system pressure, fan size and speed, etc. All of those things are working together to create the temp differential across the radiator. If you pay attention to the temp differential you'll figure out what works and what doesn't.
