I will buy exactly the same model tomorrow for 700 eur.
Short story: Just go for it, it is the best tv for the price.
Longer story: I made extensive comparisons against Samsung, LG and Sony with web research (including websites which make actual measurements), various forums, and direct comparisons in the stores with similar priced tv's regarding file formats support and picture quality, as well as smoothness of android system. It came on top 🙂
Of course, this is only my opinion. Whatever you choose, be happy with your purchase and don,'t look back 🙂
