I am having hard time choosing between the Pioneer PDP-5020 and the Panasonic 50THPZ800. Comparing the two side by side the Pioneer looks better and seemed much sharper, yet most reviews I read rate the PZ800 better in color accuracy and everything else except for black level. Apparently neither model has provision for color temperature calibration/adjustment so I would think out of the box color accuracy is a big plus. The PZ800 seemed to look dull, and even in terms of white and black level, it looked worse than Samsung and Sony LCD panels within the same price range. I wonder if it was due to the relatively bright environment in Bestbuy and FS. Other than that I really can't think of any reasons why I am not impressed by the PQ of the Panny that has received rave reviews. I did play with the settings of the Panny and managed to make it looked better but still not enough to match the Pioneer in terms of sharpness and contrast.
I would appreciate comments by anyone who has previously considered and compared these two models.
