Plasma will usually have the edge for blacks. I would give the edge to LED for color accuracy, especially if it is calibrated.

If your budget is limited, you are more likely to get better bang for your buck with a mid grade plasma set. Either way, have fun shopping. Adding new gear is always a treat.
