When choosing between the LG B3 OLED and the Vizio MQ6 '23 LCD, consider that the LG B3 offers superior picture quality, which is especially noticeable in darker rooms due to its ability to display true blacks. It also has a higher refresh rate, which makes it better for watching fast-paced content such as sports or for gaming. However, the LG B3 is significantly more expensive. On the other hand, the Vizio MQ6 '23 is more budget-friendly but doesn't perform as well in terms of picture quality and motion handling. It might also not be the best choice for very bright rooms or for watching content with numerous dark scenes. If cost is a major factor and you mostly watch TV in a well-lit room, the Vizio may be a satisfactory choice, but if you're looking for the best viewing experience and don't mind investing more, the LG B3 is likely to be the better option.

The LG B3 (OLED) is excellent for movies & TV, while the Vizio MQ6 '23 (LCD) is good.
The LG B3 OLED excels in movie and cinematic TV watching because of its perfect contrast, superior local dimming, and excellent black uniformity, which make for deep blacks and a rich viewing experience in darker scenes, along with wide viewing angles that maintain color accuracy from different seating positions. Compared to that, the Vizio MQ6 '23 LCD, while having good color out of the box and color volume, falls short due to lower contrast, less effective local dimming, and black uniformity; it also offers narrower viewing angles which can be less ideal for wider seating arrangements.

The LG B3 (OLED) is very good for cartoons & animation, while the Vizio MQ6 '23 (LCD) is good.
The LG B3 OLED is particularly suited for cartoons and animation due to its excellent colors out of the box and color gamut, providing vibrant and accurate hues. On the other hand, while the Vizio MQ6 '23 LCD also offers a good color gamut, it might not present colors as strikingly due to its lower performance in color volume and gray uniformity, which can be important in animated content.

The LG B3 (OLED) is very good for news, talk, & other TV, while the Vizio MQ6 '23 (LCD) is good.
The LG B3 excels in upscaling lower-resolution content and provides very good colors straight out of the box, making it a strong choice for daily TV programs like news and talk shows where clarity and color accuracy are valued. On the other hand, the Vizio MQ6 '23 offers good performance in these areas but may not match the LG B3's prowess, particularly in upscaling and the richness of colors, yet it's a competent option for those who prioritize good quality at a potentially lower price point.

The LG B3 (OLED) is good for bright room, while the Vizio MQ6 '23 (LCD) is only fair.
The LG B3 OLED performs better in bright rooms largely due to its excellent handling of reflections, along with good brightness levels in both standard and high dynamic range content. Meanwhile, the Vizio MQ6 '23 LCD trails with just fair performance in handling reflections and lower brightness in HDR content, which can make the viewing experience in well-lit rooms less satisfying.
