A simplified example...a car with perfect 50/50 front to rear and side to side weight distribution, true type all 4 corners. Driver says “spring too stiff”. Mechanic swaps all springs for same -1k all corners.

Now, same car but true type in front, divorced in the rear, now mechanic needs to calculate for a -1k in front, the equivalent for the rear may be -0.8k. Mechanic needs to calculate the “wheel rate” by taking into account of the spring being further away/inward from the hub.

For us, there isn’t any benefit on true coilover vs divorced. One isn’t gonna make a faster or slower driver, all else being equal.
