Sony 55-inch KDL-55W900A 3D TV, $3999.
These 55-inch slices of high-def goodness are vying for pride of place in your lounge room.
They're both LED-backlit LCD 1080p televisions, although dark scenes in movies look slightly better on the Sony because the Samsung can't quite match its contrast and deep blacks. The Sony's colours are also a little more vivid, but the Samsung's whites are whiter.
Unfortunately thin televisions offer thin sound.
Both televisions employ a 200Hz refresh rate for smooth fast-moving sport and minimal blur once you set motion interpolation to low. Set it too high and people look like they've been pasted into the scene (known as the "soap opera" effect). Unfortunately Sony's MotionFlow is prone to this even at the lowest settings. Meanwhile, switching Samsung's Motion Plus from 'off' to 'clear' offers better results.

As for design, both televisions are only a few centimetres thick and feature the thinnest of edges around the screen. The Samsung's curved stand looks more stylish, but the trade-off is that it requires a surface as wide as the television to sit on or else it will fall forward. The Sony's traditional foot can rest on a much narrower TV stand.
Unfortunately thin televisions offer thin sound. The Samsung has fuller sound and also the better night mode for enhancing the dialogue, so you're less likely to feel the need to add a soundbar to boost the audio.
Both televisions feature Wi-Fi and Ethernet for online movie rentals and catch-up TV, but Samsung's extra smart TV features give it the upper hand. These include Foxtel on internet TV, Skype via the built-in webcam and a range of Samsung apps. You can even use voice and gesture commands to control the TV.

The Sony comes out just ahead on picture quality (soap opera effect aside), but the Samsung is no slouch and its impressive smart TV features will seal the deal for many people.
