Plasma vs LED displays - Black level and uniformity

Alright... this is not a scientific test... it's just me playing around with 3 display... The reality is that I have been using plasma display for many years. I use that have a Panasonic TH-42PS9UK and it always performed flawlessly even though it is not an HD set. The picture quality was sharp when sitting at a proper distance (where you could not see the larger pixels on the panel). SD and HD content looked awesome. It was time to update that set and I decided to test a Sharp Quattron LED LC-46LE810UN. I hated everything about this set once it was installed on the wall. The sound quality is awefull, the wide bezel and mirror plastic made everything reflect on it, the SD pictuer quality (from satellite) was terrible almost non watchable... In HD, it was pretty nice until I watched a 2.35:1 bluray where I noticed that the top and bottom black bars weren't uniform in their lighting (black bars had hot spots in them). Now knowing that the PQ of the Sharp was awefull in SD, I did try another LED set in smaller size. The Panasonic TC-L42D2. The SD picture was better but the uniformity of the whole screen was as bad as the Sharp. I thought black level were ok but when I compared these LED tvs agains my old non HD plasma, I was shocked on how these new LED tvs are no way close to a plasma set. So back to plasma. My choice ended up on the Panasonic TC-P46G25. Same price as the other two, the PQ was simply spectacular in HD (THX mode... wow) and excellent in SD. The skin tone ...
