Note that no suspension bushes are Nylon!!! Nylon does not flex. they are rubber or polyurethane.
IME Super Pro both last longer AND are more supple than rubber bushes available today.
Funny you should mention a specific company. I bought some rubber bushes from them before the canning. I was told "We purchase these items from the a UK wholesaler who sources these items from the OE manufacturer. We can confirm they are OE and we certainly have had no issues with them"
These pics show them after ~2000(RA bush) and ~4000 km (TA Bush). The RA bushes failed completely in the middle of the canning.

All the bushes were replaced by Super-Pro and they are still all like new.
