If all you do is watch movies, the GT30 is the one to beat on that list if you are focused on maximizing PQ. Black levels and great picture quality is what's it's all about. It's an amazing machine.
I want to buy a 60" or 65" TV, with 3D capabilities, and Internet for streaming content. Although since there is no HDMI output on any of these TVs, Internet movie streaming isn't as important of a feature since I cannot run the HDMI video through my Yamaha RX-3010 AV receiver for upsampling of lower resultion videos. I use an Apple TV to do this (or our Samsung Samsung BD-D6500 Blu-ray 3D DVD player with Internet and apps). If there are any TVs you know of with HDMI output, let me know.
That said, the number one most important feature is I am looking for is image quality. Image is paramount. We do not have cable TV, satellite, or a DVR. We use our television ONLY for viewing DVDs (Blu-ray, standard, and 3D) or streaming HD movies. So we are looking for something that will provide the absolute best "cinema experience" on the market. I've done some extensive research and read a lot of reviews, and have narrowed down my choices to these three units:
1. Samsung 60" LED 8000 Series Plasma Smart TV with 3D - Model UN60D8000YF
2. VIERA 60" GT30 Series Plasma TV with 3D - Model number: TC-P60GT30
3. LG 60" 3D capable 1080P Plasma TV - Model: 60PZ950
4. Sony XBR HX929 Internet TV - Model: XBR-65HX929
Based on my stated desire of utmost picture quality, do you have any opinions about these three models? And are there any others I should be considering?
