If you prioritize gaming performance and spend a lot of time playing in brightly lit rooms, the Sony A90K could offer you a satisfying experience although its bright room handling is just fair. For those who watch a lot of movies and want the finest dark room performance, the LG G1 shines, but it comes at a premium price. The LG G1 also includes a sleek flush wall mount, which may appeal to those looking for a more streamlined look in their home, while the Sony A90K offers flexibility with its pedestal stand that can be positioned to hide the stand or accommodate a soundbar. Keep in mind, the G1 has built-in great speakers and slightly better sound quality, which could save you from needing to invest in an external sound system. Give Feedback
