If you could choose any coil...

Still curious what would be better. Synergy, mc, or rk triple rates...
I don't mine a firm ride, but not something that jars you on bumps and roads that have small sections of washboard.

The spring cushions between the wheel and the frame.
The shock is resistance to the speed in which the spring compresses or decompresses.
Without the shock, the Jeep body would bounce too much.
Spring and shock work together as a system, so one can't be regarded without the other.
The hardness or softness of a spring, is determined by the spring coefficient. This means that every spring which keeps the same weight at the same height, would have about the same spring coefficient.
Therefore, for the same Jeep and load, there would not be much difference in 'softness'.
Differences can exist below or above the ride height:
Compression beyond the ride height may be harder, or decompression below ride height may be softer, by using dual-rate, or progressive coils, for instance.
They would still have the same softness~hardness near the ride height.
What can change the ride softness, by much more, is the shock.
The shock resists the coil movement, so the body typically moves about 1.5 up/down cycles.
By re-valving, or tuning a tunable a shock, or by choosing a different shock, its' resistance can be changed and the overall softness with it.
If too soft, the bump stops will be hit too often.
Soft is just a term, dont let it bother you. You mentioned firm, it's simply a antonym of soft on this forum and a few others. People enjoy following another persons lingo, and most of the time they get the lingo from well known forum moderators or friends.
My suspension isn't unique -- Full Traction 4" lift and Fox shocks -- but with properly re-valved shocks, the Jeep is definitely softer than a similarly loaded stock Jeep.
Matching your shock to your spring rate is the best bet, but most people don't give out their numbers. Then your shock has to be re-valved, and most people don't want to spend another 100-200 dollars to do so.

The spring doesn't keep the tire on the road, the weight of the Jeep does. The spring cushions between the wheel and the frame.

Shocks that can be tuned by the driver, by turning a knob, are, IMO, the best option.
