Porsche vs URO 964RS Engine Mounts - 3x price worth it?

I replaced my URO 964 RS engine mounts as it was sagging after only 2 years. But will the Porsche brand eventually sag also? It cost $600 vs only $90 for the URO brand. I know these 964RS engine mounts were not designed for the heavier water cool engines but many people have upgraded to them without issues. The question is how long before they sag?
