Go to a store where you can see them side by side. The differences may be astounding. I’ve spent hours comparing them, and I’ve found Samsung to be the best, followed by Sony, then Panasonic. Look at how well each maintains clarity and detail in the shadows, while giving you a rich black. You may find that some are too low contrast and flat, while others are too high contrast, with blown-out details due to over-sharpness. Also look at any artifacts that may follow images that move quickly. A TV with a 120Hz refresh rate will be better for high-action video.
