LCA bushing Poly or Rubber?

Hi all,
I'm a new guy here and this is my first posting. I have been a Mopar guy all my life but believe it or not this is really the first A-body that I had to do these on. The last set I did was on my Road Runner 25 years ago (still have the car too)
Ok so here is my question things have changed and materials have improved and gotten better so when I did my LCA bushing I used the Moog rubber ones because I was told the poly's would wear out and squeak like crazy. So today I have ordered the energy suspension poly bushing kit but was going to use the Moog rubber bushing for the LCA. I do want to up grade to these bushing but now I'm wondering if I use the poly bushings my life will be much easier (ill not have to chile out the old sleeve) but now i'm told they could creep out. Does anyone have any experience with this.
