You have to know that for the 3d aspect, Samsung and Sony are similar (active 3d) but LG is different (passive 3d). Active 3d tvs produce flicker which is normal and they come with battery operated glasses. On the other hand, passive 3d tvs are flicker free and come with lightweight glasses. Some people say active 3ds are better in picture quality but for me they're just the same. I have my own lg smart 3d tv and my advice to you would be to choose a tv not just because of 3d alone. Consider other features. I got my tv because I liked its overall quality and features. It would also be best to go to the stores and try them personally to find what suits you best.
