OLED is my choice. Not even close. Even in-store demos will show OLED to be best.
The top LED/LCD stuff may be close, but given street prices these days, almost as expensive as OLED.
LG is apparently selling panels to other builders, too, since apparently production yields are 'up'. I've heard about a Panasonic OLED, but can't confirm.
I'm waiting for post-Christmas SALE to pull the trigger.
