they're generally harder then the rubber ones, or have different elasticity
characteristics. Can alter things like ride quality.

Do they make the ride firmer?? or just different?

i was under the impression that they perform almost identically, but last a
lot longer.

There are two types of polyurethane bushes. The original red type are a lot
harder than the rubber they replace, and will give a harsher ride. The more
recent blue variety are designed to give an identical ride to the original
rubber ones.
My experience is that in some positions they are long lasting, but in others
they do not last as long as the rubber. Also, they are more prone to
wearing the hole they fit in than the rubber ones.
The one definite advantage of the polyurethane bushes is that they are
easier to fit or replace.
Note however that there are a number of different brands of both colours and
the quality and durability do vary.

Mind, there are those who advocate using the originals only.

meanwhile, on the subject of harsh ride...

been playing with he new (to me) minibus - talk about harsh ride. Fitted a
size larger front tyres, run at lower pressure (40 lb, at the moment,
instead of the 48 the book says, and reduced the rear pressures (vehicle is,
to all intents, most of the time unladen) to 34 (twin wheels) - the book
says 50-odd for them, which might be right if you have 1½ tons in the back,
or in the case of a bus, a dozen fat bastards. They were at about 46, which
felt way too hard on the road. 34 rides much more nicely, and the tyres
don't look noticeably soft, either.
