Now, as far as cost goes, Vizio has an advantage, but I would gladly pay the extra money if the samsung has the upper hand in other areas.
I am looking for a tv that has low input lag and a decent picture. I am going to be doing a lot of gaming, both console and PC, on the TV. I have read mixed reviews on both TVs, so I just wanted a second opinion before I went ahead and bought one.
In this case, I would definately spring for the Sammy. Low budget vizio monitors use lower quality LCD panels. You will end up with a lot of light bleed around the edges, uneven backlighting, which leads to poor blacks/shadow detail. For your price range, I would actually suggest the Sony BX330 as well.
