Which is better for gaming, the C5 or the C6?

The C6. Both run 120Hz native with 0.1ms response and four HDMI 2.1 ports, but the C6 allows VRR up to 165Hz for PC gaming versus 144Hz on the C5.

Is the C6 worth about $181 more than the C5?

Only if you want the newer Alpha 11 processor, webOS 26, the 2.2-channel speakers and the higher VRR ceiling. The panel type and port count are the same, so the C5 covers most buyers.

Which has better picture quality?

Both are 65-inch 4K OLEDs with self-lit pixels, Dolby Vision and near-infinite contrast. The C6's Alpha 11 processor and Bright Room Ready tuning are the main edge; the C5 is not a large step behind.

Which one do owners rate higher?

The C6, at 4.8 out of 5 from 900 ratings, against 4.2 out of 5 from 269 ratings for the C5.

Do both support Dolby Vision and Dolby Atmos?

Yes. Both list Dolby Vision, Dolby Atmos and FILMMAKER MODE. The C6 adds a 2.2-channel, four-speaker system.

Neither has a published lifespan advantage. Both are OLED panels with the same 0.1ms response and 120Hz native refresh, so expected life is similar; the C6 gets webOS 26 versus webOS 25 on the C5.
