The LG B3 OLED presents superior picture quality and performs exceptionally well in dark rooms with its ability to display true blacks. It's also great for viewing angles and offers upscale voice command features. On the other hand, the Samsung Q70A LCD is a more budget-friendly option with decent picture quality but may not perform as well in dark environments due to its inability to produce the same deep blacks as OLED. It's better suited for bright rooms, as it can handle reflections well, but has narrower viewing angles and lacks voice command interaction. If you prioritize top-notch picture quality and can afford a higher price, go for the LG B3 OLED. However, if you're looking to save money and need a TV that performs well in a brighter room, the Samsung Q70A LCD could be adequate. Give Feedback
