D & Ep, sorry I didn't say hello tonight but you guys were deep in conversation...haha

The S2K does have a nicer finish to the interior but a slightly harsher ride. The Z definately has a stronger feel at first push of the throttle and of course the S2K starts to get fun in the high RPM range...It totally going to depend on getting some seat time in both and deciding which style you want for your purposes.
