That's a nice panel! All I can tell you is that a friend of mine...who also owns a high-end custom install shop, was invited by Pioneer to compare a bunch of panels (6 I think) different manufacturers...Panny, Sony, Sharp etc and a Pioneer Plaz as well. Along with several other industry peeps. All of the TVs were 1080p, demo'd with the same source material. Each panel was scrutinized heavily...colour, contrast, video processing, refresh rate, blah, blah for quite some time.
At the end of the session, they all agreed that every panel was good, but the Pioneer was still way out in front...in nearly every category. It was at this point that the staff conducting the session revealed that all but one panel was 1080p...the Pioneer! It was in fact a 720p panel!!!
So, don't put all your eggs in the 1080p basket. There's a lot more to a panel than just that number.
