Which do you prefer rubber or poly cab bushings and why?

[HeavyHauler]

I am getting ready to replace my cab,bed and front radiator mount bushings in my 1968 Chevy C10.

I am wondering if I should go polyurethane or rubber like the factory used. The poly of course sounds good in that I would not need to replace them again but I am wondering how much that would change the ride quality of the truck or is that more a function of quality shocks?

Which did you install and could you give me your input as it is appreciated and thanks!
