Poly Lower Control Arm Bushings VS Rubber

Ive been searching all over to see why people say not to use the Poly LCA bushings and put Rubbers in, but I cant seem to find a clear answer. I bought the Energy Suspension Poly bushings for my Duster and Im actually about to start sand blasting and reinstalling the LCA's. I saw a few people say go with the MOOG bushings just for the LCA. But why? Is it just a personal prefrence to how it rides? or are the Polys not built right for the LCA? If anyone can explain that to me id appreciate it. Thanks!
