I love our LG. Best way to pick is check the display model, see which on looks good to you and buy it.
While there's nothing wrong with doing side-by-side comparisons of display models in the store, this is far far far from the best way to pick a good TV. In fact, it's often listed as one of thing things "not to do" when buying a TV (or at least, don't rely on it alone). Check the actual stats on the range of brands/models you're looking at *first*. The display model examination should really just be about looking at the style of the bezels, colors, controls, where the inputs are, whether the stand will match the drapes, etc.
Unless your living room is lit by high powered florescent lighting, you cannot possibly get a good comparison of the actual visual qualities of the TVs while on a display room floor. Not to mention, you have no clue how whacked out the settings on each TV are. It's a common practice for stores trying to get rid of back stock of older or lower performing models, to deliberately crank up the colors on the crappy TVs and turn them down on the good quality ones. This makes the cheap/crappy ones look "great" under florescent lights, and if you don't come armed with some actual information about the sets themselves, you'll think you're getting a much better deal than you really are.
And that's beyond the common tactic in stores of chaining a whole bunch of TVs on a single signal line. Even with no intent to deceive customers about the relative quality of the TVs themselves, this will change the actual picture quality dramatically based purely on where the TV happens to be in their display area.
Look at the stats. Read reviews. That's the best way to make a decision. Edited, Oct 31st 2011 5:30pm by gbaji
