If you prioritize a variety of viewing angles and exceptional dark room performance, the Sony A90K is a great choice, although its performance in bright rooms is just fair, which could be an issue if you plan to watch in a sunny room. However, it doesn't support Dolby Atmos, a feature that can enhance the audio experience, especially in movies with rich soundscapes. On the other hand, the LG G2 excels in bright room scenarios and offers superior sound quality with Dolby Atmos support, making it more suitable if you enjoy cinematic audio and have a brightly lit viewing area. It also has a better price point, saving you money. Both TVs have excellent overall picture quality and gaming performance, so your decision might hinge on whether you value better integration with advanced sound technologies or a slightly lower price with the LG G2, versus better viewing angles with the Sony A90K.

"When it comes to picture quality alone, the LG G2 is absolutely among the best OLED TVs we've ever seen. You're getting a set that's basically impeccable across every aspect of its performance, it's truly one of the best TVs on the planet. The Brightness Booster Max technology really pays dividends to set it apart from the crown. The LG G2 is a superb OLED TV that delivers exceptional HDR performance with bright specular highlights, and incredibly accurate dynamic tone mapping."
