The LG G3 OLED will cost more, but it offers great speaker quality and slightly better performance in bright rooms. For gaming, the Samsung S90C OLED is superior and generally costs less, but its overall bright room performance isn’t as strong as the LG's. Both are excellent for dark rooms and have similar picture quality for movies and sports. If gaming is a priority and you'd like to save some money, consider the Samsung. However, if you're after better sound and bright room viewing, the LG might be the better option. Give Feedback
