I have a Samsung UN60F8000. I am wondering if I would be doing myself a disservice by getting the new Vizio M-Series 4K display, 65". There is a 2 year age gap so there are no comparison sites to reference. Anyone have any insight on this? I have read the mostly positive reviews on the new 2015 Vizio 4K tvs, and know about the firmware upgrade that does supposedly fix some of the Video processing issues that I originally heard of.
