The Sony A90K, with its upper midrange price, excels in overall picture quality, especially for movies and sports, thanks to its OLED panel which provides high contrast and good performance in dark rooms. However, it doesn't fare well in bright rooms. If gaming is important to you, it offers a very good experience. Though it shines in upscaling and motion processing, it may not be the best choice if you're looking for a TV with great speakers or if cost is a major concern. On the other hand, the TCL S455 is a budget-friendly LCD TV that is adequate for casual viewing and bright environments but falls short in gaming, motion processing, and when displaying HDR content, with its performance being just fair across most areas. It's well-suited for those who prioritize cost savings over advanced features and top-tier performance. Give Feedback

"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 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.
