If you prefer deeper blacks and more vibrant colors for movie watching, especially in darker rooms, the LG B3 OLED is a superior choice due to its OLED technology, but it's more expensive. Conversely, if you want a TV that's more suited for bright rooms and are looking to save money, the Samsung CU7000 LCD may be the better option, although it won't offer the same picture quality as the OLED, particularly in terms of contrast and viewing angles. For fast-paced sports or gaming, the LG B3 OLED typically provides smoother motion handling. Give Feedback
