A:
The PN60F5500AFXZA ((( the 5500 )))
is Wi-Fi Ready and 3D Capable
The PN60F5300AFXZA ((( the 5300 )))
is not.
The 5500 has 3 HDMI inputs and 1 shared RCA ((( 5 Cable Composite OR 3 Cable combined )))
The 5300 has 2 HDMI and 1 shared RCA
I used the Compare feature on BBY's WebSite and paste the URL below ((( But I'm not confident it will post with this message )))
If it does, you can see how the Picture Quality is very close to Identical
I recently purchased the 5300 i/o the 5500 because any of the Wi-Fi Ready Features/Programs were already available on my Blu-ray Player.
So I saved the $350 when I purchase the 5300 on 27-Dec 2013 ((( and spent $250 on the BBY Geek Squad 5-Year Extended warranty )))
The picture is outstanding ((( on both )))
I hope this helps!!!
