Just FYI OP, I heavily researched all TVs before buying mine, and be aware that pretty much all panels used by Sony, Samsung and other less known manufacturers use VA panels. LG uses its IPS panels in its Smart TV series, the difference is quite obvious. IPS panels are brighter, have better viewing angles, and their passive 3D looked magnificent and brighter compared to active 3D offered by both Samsung & Sony (both were considerably darker).
Of course, you don't really need a SmartTV+3D which will significantly increase the cost. Just research their latest panels in different sizes and then make your decision.
Always remember, in the end, its only you who will either regret your decision or feel satisfied with your decision. We can only offer you our past experience without any bias towards a particular brand.
