Is the C6 worth $430 more than the C5?

Mostly for the extra 10 inches of screen. The Alpha 11 chip and 165Hz VRR are real upgrades, but the size jump is what you notice every night. If 55 inches fits your room, the C5 is the better value.

Which is better for gaming?

Both have 0.1ms response time, four HDMI 2.1 ports and 120Hz native refresh. The C6 edges ahead with VRR up to 165Hz and the newer processor. The C5 still handles 4K 120Hz consoles well at 144Hz VRR.

Which is better for a bright room?

Both use OLED evo panels with Bright Room Ready brightness boosting and an anti-glare coating on the C5. Neither matches the peak brightness of a high-end Mini-LED, so a sunny room favors a QLED or Mini-LED set instead.

How far should I sit from each?

About 6 to 8 feet for the 55-inch C5 and 8 to 10 feet for the 65-inch C6. If your couch is more than 9 feet back, the C6's extra size is worth the price.

Do both support Dolby Vision and Dolby Atmos?

Yes. Both have Dolby Vision, Dolby Atmos, FILMMAKER MODE and a 2.2-channel speaker system. Plan on a soundbar for either if you want real bass.

LG rates both OLED panels similarly, and neither listing gives a rated panel life. The C6's newer processor and webOS 26 will likely get software updates longer, which matters more than hardware wear.
