The actual NVH itself might not be as noticeable as you might think, but delrin can be a bit of a pain to maintain on a part that moves a bit. Once it dries out, it squeaks TERRIBLY and you have to be more diligent with greasing and maintenance. A daily driver will retain grease better and provide a better experience with a poly sway bar bushing vs delrin. These were not really designed with street cars in mind.
When I did the upgrade it included zerk fittings to install so I can keep everything greased up. The car isn't a daily, but it's seen at least a couple thousand miles since the install. But I can see someone not wanting to have to get under their daily all the time to keep things quiet.
