There are several factors that could make one monitor superior to the other. Is it my belief that the PQ will be way better on the Panny Plasma than the Sammy LCD? Absolutely. There are several reasons. 2 DayTrader already mentioned, which happen to be most important to me, which are 1) Deep, inky blacks, and 2) no motion blur. LCD's are known for motion blur. The no motion blur is crucial to me because I watch a lot of action movies with fast moving scenes, I play alot of video games, and I watch alot of sports. I also think color saturation is superior on the Panny plasmas, and they don't have the other problem mentioned by DayTrader, which is the uneven backlighting.
There are things about the LCD that you'll probably miss though. You have a much greater chance of burn in on a plasma (or image retention). So with a plasma, there's a break-in period that most stick to in a way of avoiding this. Also, glare is a big issue to alot of people. If you're viewing the Sammy LCD in a well lit room, you probably won't have near the glare that you will in the same well lit room while viewing this particular model of Panasonic Plasma. You can go a step up in price range and get the anti-glare, but it still won't be as low-glare as the LCD.
Another thing you may be concerned with is viewing angle. LCD's have a very limited viewing angle (not so much with newer, high-end models, but I'm sure you've noticed this on a 2-year-old Samsung LCD). This Panasonic Plasma has no such issue. You may view the tv from any angle and see the same image quality as if you were sitting right in front of it.
Finally, you should consider how much you'll notice the difference between a 720p television and a 1080p television. I personally can not tell the difference at anything under a 50" screen size, but you may be able to. Especially if you've been watching blu rays and playing video games in 1080p for 2 years. But will you notice an improvement in the depth of the picture, the deeper blacks, and the faster refresh rate by switching to the Panasonic Plasma? Definitely. Hope this helps you're decision making.
