The Samsung S90C excels in gaming performance and has a higher overall picture quality, which makes it suitable for gamers and those looking for a visually impactful TV. It also does slightly better in bright rooms compared to the Sony A80K. However, Sony's A80K offers excellent motion processing, making it a strong choice for watching sports. It also has better built-in speakers and any sound quality. Both TVs offer OLED display technology, ensuring deep blacks and impressive contrast in dark environments. They come at a premium price and are similarly priced, so choosing between them depends on whether you prioritize gaming performance and a slight edge in bright room viewing (Samsung S90C) or motion handling for sports and better sound (Sony A80K).

USA Today

Michael Desjardin | December 2022
"It’s a high-end TV through and through something that becomes clear the moment you glance at its stunning picture. The A80K’s surgically precise contrast control is likely the first thing you’ll notice about its picture ... every piece of content looks better when this amount of precision is available. Color accuracy is another strong suit; the A80K features fantastic out-of-the-box color accuracy in the Custom picture mode."
