The LG C2, being an OLED TV, will offer better contrast and black uniformity, making it excellent for movies and gaming, especially in darker rooms. Its wider viewing angles also make it suitable for larger groups. However, it is not as bright as the Samsung QN90A, which could be a disadvantage in very sunny rooms. On the other hand, the Samsung QN90A, with its LCD screen and better SDR and HDR brightness, will perform well in bright rooms and is still a good all-around TV with solid performance for sports and gaming. It does not support Dolby Vision like the LG C2 but does offer HDR10+ support. Both TVs are premium priced and offer similar features like HDMI 2.1 support and low input lag for gaming. Your choice may ultimately come down to your specific preferences for contrast versus brightness and the types of content you watch most often. Give Feedback

Although they have very similar scores, PerfectRec considers LG C2 (OLED) to be excellent for news, talk, & other TV, while the Samsung QN90A (LCD) is very good.
The LG C2 excels in upscaling and SDR brightness, making it a more suitable choice for viewing in environments with lower light levels and for displaying content from lower resolution sources with excellent clarity. On the other hand, the Samsung QN90A, despite its very good performance in these areas, particularly shines due to its higher SDR brightness, which makes it a better fit for well-lit rooms, although it may not upscale lower resolution content as effectively as the OLED.

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."
