I've got both. I like both. They both sound different, yet similar. Words can't really describe them....but I'd say the JP6 sounds more "femine" and the MKS80 has a soft "orchestral" quality to it. For bass i would choose the MKS. Huge, fat, sweet bottom. For clicky, s***** short sequencery sounding lines - the JP6 all the way. Love both those synths! I haven't noticed a clicking on the attacks of the JP6. Not sure why. I once gave my JP6 away. Long time ago. Then I scored it back for nothing! This was long before analog synths became "vintage". Back then they were just old. I've got to say, that along with my P5, the JP6 is one of most beautiful synths I've ever owned - visually.
