I have the curved one and love it. The curved one has much better uniformity compared to all the non-curved 4K 2014 display models I've seen in stores (they all had some degree of banding and faster color washout when looking at an angle). Plus the curve is sexy.I need some help. I have read and continue to read through these threads and I'm no closer to a decision between these two sets. Both fit in a cabinet I have; The 75 perfectly and the 78 with some molding removed. I know the 78 has a few more features (and of course the curve). Personally I don't love the curve and there is the conundrum. Go with the 78 for the extra features or save some money and get the 75. Is there really a big difference between these two? Any help is appreciated.
