Simply the fact the spherical bearings allow rotation/movement along more than one axis. As Josh said, the delrin mounts only allow movement in one direction. I have the spherical bearings installed and I am still able to get the desired toe settings.
Regarding "solid" mounts I'm a firm believer there needs to be play SOMEWHERE in the system. If everything is solid the vibrations get transferred right into the mounts and THEY WILL ultimately fail (low-cycle fatigue). As Ted said, you want some movement at the differential cover or you will break the mounting points. I only went with delrin subframe bushings was because the stock ones needed to be replaced and I could get both delrin bushings for less than the cost of one OEM bushing.
