I have gone through lots of TVs over the last few years, especially since they have become more of a gadget rather than just a TV.
My first bit of advice is avoid LG like the plague. The price looks good, that's it. The first one I had was a 32" LCD smart tv Freeview HD, which had an odd sound interference issue, almost like radio inerference or static. I then went for a 42" LG passive 3D led Freeview HD smart tv. Smart TV functions was slightly better, access to App store, but when I was using the TV tuner as a source, the TV decided to turn off and on about 3 times in the first hour before it settled down, and then I got some what I think was vertical banding. The passive 3D is good as the glasses are cheap and require no batteries.
Now I have bought a Samsung UE40F6320 -which has a 46 inch version UE46F6320, or you could go for a very similar model with added voice control
I didn't realise that there was one for very slighty more with voice control until I got this one, but I am very happy with it all the same, two pairs of active 3D glasses, and the full UK catchup TV services, Netflix, Lovefilm etc.. Samsung is the only one who has the full lineup of catchup TV services on their smart TV sets.
below is the link to the 46" version with Voice control (review)
