I took a car for a test drive the other. It had 3 suspension settings at the press of a button - Comfort, Normal and Sports. The Comfort setting gave the smoothest ride on the rougher road while the Sports setting was choppy. But on a really good surface, the Sports setting was best, as the Comfort setting sort of wallowed and rolled. Your question is not easy to answer; I doubt there is a simple "best". It depends on where you'll be riding, how you'll be riding, how much weight you'll be carrying etc. And how much you want to spend. A lot of people swear by a particular brand/type yet there's have tried them and hate them - for a whole lot of different reasons, including service and serviceability, not just ride and handling.
