Summary: I bought 2 new tv's...A Vizio 42" smart led 3d tv(120hz) and a LG 60" smart plasma (640hz)TV (PM6700). The picture on the LG plasma is much better in my opinion. The picture seems more vivid and realistic and the action is extremely smooth. The picture on my Vizio is also very good but the action is not nearly as smooth. The 3d on both tv's is also very good. Overall I would buy a plasma over a led. Plasma's cost less and have a better picture in my opinion.
