Have a ZZR600-----but have never ridden either of the other bikes you mentioned----so can't really give a comparison though.
I like mine--just enough speed to give you a thrill---but slow and heavy enough to keep the wheel on the ground and give a fairly smooth ride.
Also---not all stretched out riding position--like the "R" models---fairly comfortable---but my hands start to go numb after some time in the saddle.
