A:
The EH5300 is a 2012 model, and the F5500 is a 2013 model - probably the most significant difference would be in that specification. While both have Smart Apps, the F5500 model has Smart Apps 2.0, which is an upgraded platform for Apps and connectivity. In short, you can explore and use more Apps with the F5500.
Both models have Wi-Fi, 3 HDMI ports and 2USB ports already built in.
if you have a specific question between the two models that we can help with further, we'll be happy to address those. Just let us know how we can help.
Thanks for your interest in Samsung televisions.
