Hydractiv vs Hydropneumatics

Hello, I used to drive xantia 2.0 vsx automatic 121 ps with the hydraulic suspension. that’s been a long time ago, from 1993-1996. the car was simply great. though, the car had matured the 195/55s at that time, which were not useful to the comfort. I want to get another xantia now. therefore the question to the experts among you, or also to those who have popo experience. wants to name: which of you has driven both types, so one with hydractiv and one with normal hydropneum atik and can I describe the difference I felt? I am a comfort fetishist. the more floating, the better. can you bring the normal xantia with comfort balls to the floating eye of a hydraulic? or even increase it? thank you for your infos, olaf
