If you're talking quality, Sony's better! first and foremost, nothing beats the quality of the image (other than a sharp aqous perhaps)...response time is decent at 8 ms (which is slightly worse than the samsung's 5 ms, but still good enuf to prevent "streaking" for high action flicks/sports games)...and more inputs as well...
Samsung definitly has a better response time as mentioned earlier, and is a bit cheaper than the sony...so if the additional inputs aren't needed, and the image quality difference isn't a big factor either, samsung is a better deal...
also, sony's dynamic contrast ration is 25000:1 compared to Samsung's 30000:1...not a big diff in my opinion...actual contrast ratios would be 2500:1 and 3000:1 respectively...
i'm assuming u have some prices already for both of these?
