Does anyone have SACHS shock absorbers fitted?

I continue with my search for shock absorbers, in the beginning the idea was the Koni Special Active or Bilstein B12, but I already used the Bilsteins in a Ford Focus and after 3 years they became hard and uncomfortable.

I do not know if the Koni will be too hard to travel as a family.

Now a friend has ridden Sachs twin tube and says the car is firmer and drives better than the garbage ZF shock absorbers. Will they be like the Bilstein B4?

In any case, to make matters worse I carry the PPD suspension or for roads in poor condition and I don't know what springs other than the Eibach Pro kit to put to lower the car a bit, since the normal or sportline in Skoda are worth more than 500 euros , just the springs.

Thanks in advance.
