I recommend you to purchase second one ,"Sony KLV-40R562C 102 cm (40)" as it has more connectivity and internet options than other one, "Panasonic".
It has 2 USB Connectivity portals, Analog Audio Inputs for HDMI's.
Wireless-LAN built-in; Ethernet Connection: 1 (Rear)
Applications-Youtube and Opera Apps.
Photo Sharing Plus: Photo, Music, Cinema, Game, Graphics, Sports, Auto; Clock; Sleep Timer; On/Off Timer; Screen mirroring and MHL to see your smartphone's screen on BRAVIA, with no wire; BRAVIA Sync.
More Playback Formats.
In my opinion, Sony is the best option if you want more connectivity options or internet access or more video playbacks formats.
