The Samsung CU8000 offers more advanced features and tends to be on the more expensive side. It's a good fit if you're willing to invest in a better streaming experience, and it also boasts a faster response time, which is beneficial for gaming. On the other hand, the TCL S455 is more budget-friendly and offers good performance for its price. It might not match the Samsung in terms of features and speed, but it's a solid choice if you're looking to save money while still getting a quality television. Give Feedback

The TCL S455 (LCD) is only fair for movies & TV, while the Samsung CU8000 (LCD) is poor.
For watching movies and cinematic TV, the Samsung CU8000 has less impressive blacks and local dimming which can reduce the picture quality in dark scenes, while the TCL S455, though better in those aspects, may not display colors as richly and variously, affecting the overall vibrancy of the image. Both TVs may struggle with color accuracy out of the box and viewing angles, making them less ideal for wider seating arrangements or critical viewing.

The TCL S455 (LCD) is only fair for news, talk, & other TV, while the Samsung CU8000 (LCD) is poor.
The Samsung CU8000's fair SDR brightness and lack of local dimming lead to a less robust picture quality for news, talk shows, and regular TV programs. In contrast, the TCL S455, although it shares a fair SDR brightness, benefits from better upscaling and a higher contrast ratio, which slightly enhances the overall viewing experience of similar content.

The Samsung CU8000 (LCD) and TCL S455 (LCD) are both only fair for sports.
The Samsung CU8000 has a poor response time which affects the clarity of fast-moving scenes, a significant drawback for sports, but it has a considerably low input lag for less delay in displaying content. In comparison, the TCL S455 features fair response time providing better motion clarity for dynamic sports action but struggles with reflection handling, resulting in potential glare issues in bright rooms. Both TVs might display inconsistent shades of gray across the screen, impacting the uniformity of sports fields or courts. Viewing angles are limited on both models, leading to color and contrast shifts when viewed from the side.

The TCL S455 (LCD) and Samsung CU8000 (LCD) are both poor for gaming.
The Samsung CU8000 has a poor response time, making it slow to render changes in fast-moving scenes, which is not ideal for gaming where speed is crucial. On the other hand, the TCL S455, while offering the best input lag, which is good for quick reactions in gaming, also has a fair response time, which can result in slight blurring during fast action.

Although they have very similar scores, PerfectRec considers TCL S455 (LCD) to be only fair for cartoons & animation, while the Samsung CU8000 (LCD) is poor.
The Samsung CU8000's colors out of the box are rated fair and it has a good color gamut, suggesting that it displays a wide range of colors decently well immediately after setup, which is important for animation. On the other hand, the TCL S455 also has fair colors out of the box but a poor color gamut, indicating it may not showcase animation as vibrantly due to its limited range of colors.

"A highly affordable but reliably kitted-out 4K Roku TV that, while far from perfect, still punches above its price and delivers a great user experience. If you want to soup up movie night for a bargain, the 4-Series won’t let you down. You may never need to plug in a set-top box or streaming device."

About Samsung
Samsung, a South Korean electronics manufacturer, holds the title of being the largest global TV vendor in terms of units sold. They offer a diverse lineup of TV products that cater to various budget ranges. A notable achievement in recent years is the development of Quantum Dots, a technology that enhances color reproduction, resulting in richer and more vibrant hues. Samsung TVs are well-regarded for their high manufacturing quality and user-friendly software, making them an excellent choice for consumers seeking an intuitive viewing experience.
About TCL
TCL, the highly recognizable TV brand from China, has firmly established itself as the second-largest manufacturer in terms of sales volume. Renowned for striking an impressive balance between affordability, picture quality, and design, TCL TVs deliver a compelling overall package. While they have traditionally excelled in the low-end and midrange TV segments, TCL has recently made remarkable strides in the realm of high-end televisions, introducing impressive models that rival top competitors. Most TCL TVs use Roku software which is very user friendly and easy to use, but they have a few other models that use Google TV which has the largest app selection, but is not as user friendly as Roku.
