The Samsung F5500 Plasma TV has the same panel as the F5300, but comes packed with more features. It adds 3D and Samsung's Smart TV interface. The screen still reflects a lot of light, so you will need a dark viewing environment to enjoy it.
The Samsung F5500 Plasma TV has the same picture quality as the lower F5300 model. This means very good picture quality in a dark environment, but a washed out picture when the lights are turned on. Unlike the F5300, though, this TV has a smart TV interface, as well as 3D.
Though it can get brighter than the Panasonic S60, it also has more reflections.
