A:Answer The KS9500 is Samsung's best 2016, with quantum dot technology with wide color gamut, HDR support and a 120hz panel with en effective rate of 240hz. The JU6700 is Samsung entry level curved 2015, it's your regular LED with a 60hz panel refresh rate and an effective 120hz. The KS9500 is a much better model, however the best one I would recommend would be the JS8500, JS9000 or JS9500 which is Samsung's better 2015 TVs. If you are torn between the KS9500 or JU6700 I would go KS9500 however personally I like the JS9000 as a better TV overall between the two you listed.
