I never had the aluminum ones on my car. Bought aluminum first, then I found the MMR plastic ones and decided to use those - i heard they're a bit softer than aluminum. In fact I think they are equally hard, because I was able to just torque the subframe nuts straight onto the plastic bushings without any steel inner sleeve (remember stock rubber ones have an inner steel core), just like the aluminum.
There's a bit of clunks and whines, but I can't tell for sure it's due to the bushings, or my pinion+ring gear backlash. I got a new diff and am having it checked at a transmission shop, so when it's on I can tell you some more
I guess it doesn't matter if you get alum or plastic, they both remove all the subframe play. All the alum ones are pretty much the same. Heck, any company can easily measure dimensions off another product and CNC their version.
