My sister asked for my input on the very same question, although she wanted a smaller TV. At the time, which was a couple months ago, I suggested my sister picked up one of the new Samsung's.
From the research I did on the net, perusing many forms, I came across many people suggesting them based on price/performance.
Now, I've never done a side by side comparison, that's just what I've gathered from online.
Hope that helps.
Take it easy.
