I've owned both very recently. I sold my 1000S and bought a 650N. The only thing better about the 1000 in my opinion is if you often ride two up. The 650 is smoother, lighter, handles better, cheaper to own and insure, and a little better at the fuel pump. I seriously think I am quicker on the 650 when the roads get twisty. All around, I think the 650 is much more fun.
