Then you need to consider damper types: twin tubes gas pressurised or atmospheric, monotubes gas pressurised or atmospheric & specials where the damping is also dependent on stroke etc. They all have different responses with respect to rate of change of velocity, ie how fast they give force for a velocity input. For a road car you want them to respond relatively slowly to give good ride over rough surfaces but for a race car respond quickly as you are going faster. Difficulty is to make a responsive damper like a gas pressurised monotube Bilstein give good ride but then work well when driven hard - it is done!
Any of the above damper types can give the same force;vel curves, but it is the transients and change in characteristic with heat that are the differences. Pays your money, takes your choice and do the road testing for the spring rate and car weight in mind. Hours of fun and many hundreds/thousands of miles of testing.
