Here's a slightly different take. When deciding on my present TV, I went to the numbers, for better or worse, as well as others' experiences. The numbers come from factory specs, so may not be totally accurate (they arealways fudged between optimism and liability), but are probably fairly precise (done the same way across brands).
For those interested in the numbers, here is a thread (with spreadsheets) and
an application.
