If you are looking for a TV that provides value for money with excellent performance in a dark room and for movies, the Sony A90K (OLED) could be a great choice, and it's less expensive than the LG G3 (OLED). However, the LG G3 (OLED) excels in a bright room and includes a sleek flush wall mount instead of a stand, which might appeal to those prioritizing a premium build and design. Both TVs offer OLED technology with top-notch picture quality, but if superior audio through built-in speakers and advanced features like voice commands are important to you, the LG G3 holds an edge. Keep in mind that the LG G3 is a newer model with potentially more recent technology. It's essential to weigh the importance of price against these attributes when making your decision. Give Feedback
