The Samsung Q70A is a more cost-effective option and offers a good performance for gaming, sports content, and bright room scenarios. It is an LCD TV however, which means it may not provide as deep blacks for movie watching in dark rooms compared to an OLED. On the other hand, the Samsung S90C is a premium OLED TV, which generally means it will have superior overall picture quality, perfect blacks for dark room viewing, and excellent performance for gaming, sports, and movies. However, it is usually significantly more expensive and might not be as bright as some LCD TVs in very bright rooms. If you primarily watch movies in a dark environment, value perfect blacks, and are a heavy gamer, the S90C is a great choice, but if you're looking for a more budget-friendly option that still offers good performance in bright rooms and for sports content, the Q70A would be a solid choice. Just be mindful that the OLED will likely offer a noticeably better picture in most viewing situations. Give Feedback
