If you're looking for exceptional picture quality, especially for movies and gaming in dark environments, the LG C2 might be the choice for you, although it comes at a premium price. The C2 offers superior contrast, perfect black uniformity, and wide viewing angles which is typical of OLED TVs, but it may struggle more in bright rooms. On the other hand, the TCL R646 costs significantly less and still delivers a competent bright room performance, which makes it a suitable option if you're on a budget and have a brighter living space. It offers decent picture quality and is also good for gaming, but the picture quality overall, especially contrast and uniformity, won't match that of the LG C2. Consider the LG C2 if premium picture quality and gaming performance are priorities. However, if cost and bright room viewing are more critical, the TCL R646 may serve you well. Give Feedback

The LG C2 (OLED) is very good for sports, while the TCL R646 (LCD) is only fair.
The LG C2 excels in sports watching primarily due to its OLED technology, which provides the best response time for crisp motion, and wide viewing angles which ensure a clear picture regardless of where you are seated. The TCL R646, while offering very good reflection handling, lags behind with its LCD screen which doesn't match the response time and vieweing angles of the LG's OLED, and scores lower on gray uniformity which is also important for displaying sports content.

The TCL R646 (LCD) outperforms the LG C2 (OLED) for viewing in a bright room, mainly due to its excellent SDR brightness and very good performance in handling reflections, which helps maintain picture quality even in well-lit environments. Although the LG C2 offers good brightness and excellent reflections handling, its overall capability in bright rooms is less advanced compared to the TCL R646, which also has an advantage with brighter HDR content, contributing to a more vibrant picture in sunny conditions.

The LG C2 (OLED) and TCL R646 (LCD) are both very good for cartoons & animation.
The LG C2 OLED TV excels in displaying cartoons and animation due to its superior color accuracy right out of the box and a very wide color gamut, ensuring vibrant and true-to-life visuals.

CNET
David Katzmaier | November 2022
"The C2 offers image quality that's a clear step above any non-OLED TV I've seen. The C2 is rare among high-end TVs in that all four of its HDMI ports support 4K/120, great for hard-core gamers with multiple next-gen devices. The C2 is plenty bright enough for just about any viewing environment. It also outperforms QLED TVs like the Samsung QN90B and TCL 6-Series. That's why I consider the LG C2 the best high-end TV for the money of 2022."

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.
