The Samsung F5500 LED TV is very good for the price. It has about the same picture quality as the F6300 or FH6030, despite only being a 60Hz TV. If you do not need motion interpolation or 3D and want Smart TV features, you should opt for this TV over those others.
If you do not need a wide viewing angle or fancier features, buy this TV. The Samsung F5500 LED TV has very good picture quality both in dark and bright rooms.
The only downside of the F5500 LED TV is its narrow viewing angle. As soon as you are of axis, discoloration appears. If you need a wide viewing angle, you will be better off with the LG LN5700.
The F5500 has low motion blur for an LED TV of its price. It doesn't support 24p playback or motion interpolation, though.
