The ride with the Eibachs will really be determined by what shock you go with. if you use an OEM shock it will be a pretty nice ride still, just getting rid of the "float" when driving especially at higher speeds.
If you go with a stiffer shock that is when you start to infringe into the territory where the CS may prove superior, as it is a matched spring/shock set.
We do a boatload of CS's these days, no complaints yet even from a very diverse demographic.
