This depends on the suspension setup. Hydropneumatic suspension (in implementations slightly different to Citroën's) has been used on various sports cars including the MG F and McLaren's current range including the P1.
Citroën's original implementation was biased for comfort, at the expense of body control: after a bump, the system takes longer to settle than most cars. Citroëns also tended to roll quite a bit, although that didn't impair cornering as much as you'd expect.
Citroën later developed hydractive variants (with variable spring rates to improve body control) and ultimately the Activa.
At any time, Xantia Activa rolls at most half a degree. This make it not only spectacular to look at, but also improve cornering speed. French magazine L’Automobile tested a Xantia Activa on skidpad and measured an amazing 0.94 g lateral acceleration. This compares competitively with many supercars - NSX managed 0.93 g, Ferrari 512TR 0.92 g, Toyota Supra 0.95 g and Ferrari F40’s 1.01 g. This is even more impressive if you consider the Xantia wears just 205/55R15 tyres ! Most cars in its class manage around 0.8 g only !
