On my car I have the Tarett sway bar drop links (F&R), the steering links (F), and the toe links in the rear and I am happy with them.
However, I believe that the kind of spherical (teflon/nylon?) will eventually start rattling once they start to wear down on uneven roads.
I am already on the second set of rear toe links (first set was from Rennline (installed first on the 987 and then moved to the 981), and the second set is from Tarett that were installed about a year ago.
But now I started to hear a bit of rattling on the rear end and not sure yet if the noise comes from the Tarett links, or from the OEM coffin arms, the car has about 39k..
PS: The bottom line for the OP question, for the long run I would recommend the OEM style rubber bushings, that are supplied by several good European manufacturers like Lemfolder, TRW, Mahle, oh, and by all means avoid URO..
