I would disagree
the majority of "decent" coilovers have separate height adjustment thus not affecting the spring preload, so no matter how much you lower the car the travel of the suspension will remain the same so in terms of ride quality there will be VERY minimal difference if any at all.
it's all down to the dampers, a spring is a spring, springs will behave in the exact same way regardless of what coilovers (disregard progressive springs, generally found on fixed shocks and also tender springs which are found on some race suspension (not to be confused with helper springs)), it all comes down to how well the damper controls the movement of the suspension
