Well, actually...
You can get a more comfortable ride than OEM (and slightly better handling too) by getting rid of Ford's modified McPherson struts and the live axle spring/shock combo.
With the springs up front so far inboard, the spring rate has to be pretty stiff already. By going with true coilover, you can either decrease the spring rate but still have the same effective wheel rate which in turn makes the ride even softer without sacrificing factory level handling response/traction. Or you can do the same but with a slightly higher spring rate which will make the ride only slightly more harsh but with markedly improved handling/traction.
The same is true for the rear suspension. With the springs literally sitting in the middle of the lower control arm, the ride quality and the handling is inherently crap. But if you were to get coilovers everything will improve (see above). Couple those with deleting the quad shocks, upgrading to solid LCAs, a Watts Link, and either a torque arm or an upper third link, the ride quality and the handling drastically improves over OEM.
Bushing selection still has an effect, but I'd argue less of an effect than the above points. Again, if rubber can be utilized then that's the most streetable option. But polyurethane would come in second and it's really not all that harsh. The harshest element in an SN95 suspension system by far is Ford's spring placements on the vehicle.
