I'm in the market for a new TV and needed some help in deciding which TV might be better for me. I'm looking at either the Samsung PN58C6400/6500 or the Vizio XVT553SV. We don't do any gaming, we watch movies occassionally, and we don't care about 3D. The TV will be mainly used for just general TV watching (a lot of sports though). The room the TV in will not be bright. I can get either one for roughly the same price. I've read great reviews on both, but am stuck on this plasma vs led/lcd debate. Any input is greatly appreciated.
