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).

The Samsung S90C (OLED) is excellent for cartoons & animation, while the Sony A80K (OLED) is very good.
The Samsung S90C is considered excellent for watching cartoons and animation because it offers superb colors right out of the box and an excellent color gamut, ensuring vibrant and various shades are displayed accurately. The Sony A80K, while also very good in these aspects, does not quite match the Samsung's performance, meaning colors may not be as consistently rich or accurate straight out of the packaging.

Although they have very similar scores, PerfectRec considers Sony A80K (OLED) to be excellent for sports, while the Samsung S90C (OLED) is very good.
The Sony A80K is excellent for watching sports due to its slightly better motion processing and reflection handling, which improves the viewing experience during fast-paced scenes and in rooms with many lights. In contrast, the Samsung S90C also offers very good quality for sports with comparable response time and viewing angles but falls slightly short in those specific areas when compared to the Sony A80K.

Although they have very similar scores, PerfectRec considers Samsung S90C (OLED) to be excellent for news, talk, & other TV, while the Sony A80K (OLED) is very good.
The Samsung S90C excels at watching news and other TV programs with its superb upscaling of lower resolution content and strong SDR brightness, which is important in various lighting conditions. The Sony A80K, while very good for similar content, has slightly better colors straight out of the box, which could enhance the viewing experience without the need for further calibration.

"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."
