If you prioritize the best overall picture quality and excellent performance for movies, sports, and gaming, especially in dark rooms, the Samsung S90C OLED is a great choice. However, it's not as bright as an LCD and may not be the best option for very sunny rooms. On the other hand, if you are looking for a TV that performs better in bright rooms and are willing to sacrifice a bit of picture quality and viewing angle, the Samsung QN90A LCD could suit your needs. It has a higher brightness which makes it more suitable for bright environments. Both TVs are similarly priced, so the decision should be based on the viewing conditions and content preferences.
