The LG B2 is an OLED TV which means it will offer excellent picture quality, especially in dark rooms due to its ability to achieve true blacks. It's also great for gaming, movies, and series with its fast response time and low input lag. However, in very bright rooms, its performance is less optimal compared to LCD TVs. On the other hand, the TCL R646 is an LCD TV with miniLED backlight technology which is generally more affordable than OLEDs. It's quite good in bright rooms and offers a higher HDR brightness. Though it's decent for gaming, it may not match the LG B2 for this purpose. Its picture quality drops at wider viewing angles compared to the LG B2. So, if you want premium dark room performance and gaming experience, and don't mind paying more, go for the LG B2. If you're looking for a more budget-friendly option that performs better in bright rooms, and can live with a slight compromise on viewing angles and some picture quality aspects, the TCL R646 would be suitable.

Tom's guide
Nick Pino | March 2023
"The LG B2 OLED pairs lush, saturated colors and perfect contrast with a 120Hz screen, HDMI 2.1 ports and a great smart TV platform. The LG B2 OLED is an ideal alternative to the LG C2 OLED for folks who want a taste of OLED life without the sticker price that usually comes with it. The LG B2 OLED does a lot right in terms of performance, color saturation is wonderful and contrast is second-to-none. Not only did color saturation and off-axis viewing impress me, harder to quantify specs like motion processing and upscaling really blew me away as well."

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.
