Which is better for gaming, the B6E or the C4?

The C4. It has four HDMI 2.1 ports, VRR up to 144Hz and ALLM, which the B6E's listing does not confirm. Both are 120Hz OLEDs with about 0.1ms response.

Is the C4 worth the extra $70?

Yes if your room is bright or you game on a current console. The evo panel and α9 Gen7 processor are real steps up. If you watch mostly in a dark room, the B6E saves money with the same OLED black levels.

Which has the better picture?

The C4 is brighter and has the stronger processor. The B6E still delivers perfect black and Dolby Vision. In a dark room the gap is small; in daylight it is visible.

The B6E is a 2026 model; the C4 is a 2024 model. The B6E will likely get webOS updates longer.

Do both support Dolby Vision and Dolby Atmos?

Yes. Both list Dolby Vision, HDR10 and HLG, and the B6E adds Dolby Atmos. The C4 adds Dynamic Tone Mapping Pro.

Neither has a published lifespan advantage. OLED panels on both can show burn-in from static logos over years. The C4's newer processor and the B6E's newer model year are the only longevity factors.
