James and sunama have summed up pretty much everything I think as well.
Also Robbie I must point out that an SD feed in a store will most likely be pretty crap, made up of many long & cheap cables, distribution boxes & splitters, all having an affect on the PQ. It's not like just plugging your tv at home into one cable leading to your aerial/sky dish. The quality of SD sources in shops has always been nigh on shocking in pretty much every store I have been into.
Adding to the calibration remarks, how do you know what an accurate picture looks like if you have never seen an accurately calibrated reference display ?


I'm being a bit Kuroist here, but after seeing 8G, 9G sets, and Panasonic Pf10 for over 10hrs over the course of 2 weekends at a reference dealership, I really saw how an accurate picture is meant to look. Not everyone can or wants to do this, but people saying they calibrated a set then compared them as 'calibrated displays' really isn't accurate at all.
I expect that you will burst into tears if I say I preferred a LED to a plasma once more!
Why are you trying to ignite some type of fanboi war

, we don't have any allegiance to a particular tech, or need to justify our purchasing decisions to others. We give out the best advice we can from our experience, which with number of users on here is quite extensive
The are plenty of opinions out there on sets from everyone, but there is also a general concensous from random reviewers, professional calibrators, quality and accurate reviews, then of course users/consumers. It's easy enough to read up then make some choices yourself, but plenty still listen to incorrect information from fanbois and those who really don't have anything to offer other than an opinion on why the set they personally purcahsed is the best and should be bought by all. As james has said, grouping either tech type into a fanboi generalisation is totally wrong.
