On my DC2R, i've had stock sussy, and then Koni and Eibachs, and then Buddy Club racing spec dampers, and now got Zeal Function X.

The BC and Zeals Spring rates are the same, yet due to the damper/shock design, it chopped 2.1 seconds of my lap times at Wakefield.

A shock is not just a shock. And it is a big deal IMHO.

IMO Oil shocks are FAR superior to gas shocks.

If they are for the street or something, then yeah Koni's are fine... but I much prefer the stock 'coilovers'.
