i have just replaced mine with the nolathane bushes along with every other bush in the front end. Deffinitely handles better and ride is harsher, but only a little harsher. so i would def go with the nolathane ones again.
I had the caster bar/radius rod bushes replaced in my VX SS with Superpro, first thing I noticed was how good and positive the car felt on the road, big improvement, I was a bit concerned about the ride/comfort side of things, but to be honest I don't think it has made much difference to the ride, maybe a tad firmer but not much difference at all.
