Buck, our LED TV has been great for gaming. I can't comment on how it relates to LCD. If you'd like to swing by and check it out, let me know and we can set that up.
I have an older Samsung LED, and the thing I love about it is the ability to watch programming from downloaded sources. This was made easier with the model that came out after mine, which, if using Samsung's app for mobile devices, makes it possible to not only use your phone as a remote for the TV. It also lets you watch whatever is on TV, on your phone. My TV streams from my PC to the TV over our network (wireless on anything newer than mine) or from a memory stick.
Most of this info is redundant for a lot of people reading, but I don't care. Deal with it.
