The GT30 sits in the upper-middle end, a notch below the company's 2011 flagship in panel technology and, we assume, picture quality. It's not without its flaws, but it's still a superb TV overall that sets the bar high once again--although it's not a significantly better performer than its less-expensive (albeit plainer-styled) line-mate, the TC-PST30 series. The Panasonic TC-PGT30 series belongs on the short list for buyers who want the advantages of plasma in a thin form factor but don't want to pay the premium for a flagship TV.
Update May 5, 2011: The introduction and performance sections of this review have been modified to reflect additional testing and comparison in light of the Panasonic TC-PST30 series review. The score has not been modified, however.
