Mark, your point about power consumption is a great one, as I'm extremely parsimonious when it comes to my footprint.
I knew that. Matter of fact, I was wondering the other day, "I wonder which of my friends exhibit the most parsimoniousness?" and I thought of you.
Not to keep touting the LG, but having just gone through all this...
I chose the LG over the Vizio because it seems as though some models of the Vizio had QC problems (turning off on their own, etc) and I limited my choices to brands with less reflective screens. The LG got across-the-board good reviews, had a lower-glare screen (none are actually matte) and had local-dimming...which allows some of the LED back lights to turn off to give you deeper blacks....avoiding that "gray" black that used to plague LCDs.
Vizios also have a great picture and a non-glare screen but those QC issues concerned me.
Samsung and Sony had the most reflective screens.
