If you’re planning on keeping the stock suspension components, ie, UCA’s, strut rods, LCA pivot pins etc, use rubber.
If you’re willing, or want to use adjustable strut rods and greasable LCA pivot pins, then use the poly bushings. Properly installed, the poly bushings will outlast and outperform the OE rubber. But they don’t work exactly the same way, so, you need to account for that on installation.
