Depending on how much you want to spend and what type of room you want to put it in.
Dark room = Plasma all the way
Light room = LED
I just got a new 65" Panasonic VIERA TC-P65VT50 Plasma. Nothing on the market as far as plasma can beat it. Its absolutely gorgeous edge to edge and uses a single sheet of glass w/ small bezel. The calibration you can do w/ this set is 2nd to none.
About $3500-3700 atm.
My last set was a Pany plasma as well. I moved it to the upstairs living room. The blacks even on that old tv are excellent. Its only a 1080i set but still puts out an incredible picture. One of the reasons I stayed with Panasonic for this new TV we got.
I've got a prayer on my desk. It says, "Dear Lord, I pray that my place will never be with the cold, timid souls who do not compete yet criticize, for they never know or feel success or failure."
