Choose the Sony A90K if you value excellent picture quality, especially for movies and sports, and if gaming is important to you. It performs well in dark rooms and has good color accuracy, though it's not the best choice for very bright rooms. If you're on a budget and want a TV for casual viewing in a room with controlled lighting, the TCL S450F is a wallet-friendly option with fair performance across the board but weaker picture quality and gaming features. Both TVs support HDR but the Sony offers additional formats like Dolby Vision for enhanced viewing experience. Sony's OLED will give you better viewing angles and motion processing, while the TCL's LCD display might be more durable over time. Give Feedback

About Sony
Sony stands as a highly experienced and widely trusted TV manufacturer, earning a reputation that surpasses all others. A Japanese company, Sony has been making TVs for far longs than it has been making Playstation game consoles. Sony's high-end TVs are often regarded as the ultimate choice for videophiles, representing the epitome of quality, albeit at a premium price point. Renowned for their advanced and precise motion handling, as well as their cutting-edge local dimming algorithms, Sony consistently delivers unparalleled performance in these areas. They include Google TV software with all their TV sets, which grants access to the largest selection of apps available and they also include Bravia Core which is a movie streaming platform specifically for Sony TVs that offers higher picture quality by using more bandwidth.
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.
