If you are on a budget and cost is a significant factor for you, the LG UQ7570 is the more affordable option. The LG UQ7570 has a strength in having a good wide viewing angle which makes it suitable for wide seating arrangements, but its performance in bright rooms and overall picture quality is not impressive, making it less ideal for brightly lit environments and for viewers who prioritize a high-quality picture. In contrast, the TCL S455 excels in black uniformity which could enhance dark scene viewing, such as in movies, and it also has more HDMI ports which might be useful if you have multiple devices to connect. However, both TVs have limitations in picture quality and gaming performance. Neither TV is well-suited for demanding gamers or for those desiring the best viewing experience for sports content. Consider what content you watch most, the lighting of your room, and your need for multiple HDMI ports when making your decision. 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 LG
LG, a prominent TV brand from Korea, has played a significant role in popularizing OLED TVs. OLED technology is hailed as the future of TV technology. Their TVs employ WebOS, a proprietary smart TV software that not only offers seamless functionality but also includes gaming-specific features, earning praise from players worldwide. Often regarded as the gateway to unparalleled viewing experiences, LG's mid-range OLEDs come highly recommended, making them a worthwhile investment for those willing to stretch their budget for superior quality.
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.
