Which brand wins outright is tricky to answer, but we can designate which brand has better options for your ideal entertainment environment pretty handily. If most of your TV usage will occur during the day (like gaming or watching sports), the quantum dot layer of QLED TVs offers the brightness and inch-by-inch backlighting necessary to make content pop in bright rooms. Samsung specializes in QLED and has an expansive lineup of QLED and Neo QLED 4K TVs at a huge range of price points. OLED, on the other hand, is the style of lighting you'll want if you do most of your watching or gaming in a dark room, as the self-lit pixels of OLED are able to get darker than backlit pixels to create contrast and hit the most legible black levels. LG has perfected OLED over the years and offers a more expansive lineup of OLED options than Samsung.
