LG C4 is the stronger pick if you want the larger-screen, more theater-style setup with its 65 inches panel and OLED display class. Samsung S90D QD makes more sense if you care more about keeping cost and size in check while still giving you a 65 inches 4K TV. For most shoppers, the real decision is premium big-screen impact versus value-oriented everyday viewing.
