I run the Global West aluminums. I didn't notice any hint of difference in cabin harshness or noise, etc. I think of it like the 3rd gen Camaros, the subframe is welded directly to the body on those. I decided on aluminum mounts because I was installing subframe connectors. I had previously been running polyurethane bushings for years beforehand.
Let me say this about polyurethane as well... in a MOVING suspension system, poly has a tendency or rumor to squeek.
In a body bushing situation, there's no spinning, rotating, etc. It's mostly compression dampening between the body and frame. Poly body bushings will not squeek. Period.
And if you're going to run subframe connectors, then I consider solid body mounts imperative. The last thing you want to do is have flex between your body and frame in the front, but rigid in the back.
After experiencing on my daily driver poly bushings and then aluminum mounts, I will never bother with poly body bushings again. There was no difference in ride quality, and the frame to body unity felt more strong/solid going into driveways, speedbumps, etc. But that was also helped by the connectors.
As for brand, I don't have experience with the PTFB but they look high quality. I bought the GW ones cause I first purchased the Comp Eng. aluminum mounts, but they had an almost non-existant lip and you're supposed to use a shorter bolt and washer on the bottom side. This seemed very hokey to me, so I never bothered installing them. The only other aluminum mount on the market was the GW interlocks.
