Which is better for gaming?

The LG C5. It has four HDMI 2.1 ports, VRR up to 144Hz, G-Sync and FreeSync Premium. The Samsung tops out at 120Hz and does not list HDMI 2.1 ports or VRR formats.

Is the Samsung worth it for the bigger screen?

Yes if distance matters. At $899.99 it is 10 inches larger and $70 cheaper than the C5. The C5 wins on ports, gaming features and Dolby Vision.

Which has better picture quality?

Both are OLED with per-pixel contrast. The C5 adds Dolby Vision, FILMMAKER MODE and LG's Alpha 9 Gen8 brightness boosting. The Samsung lists HDR but not Dolby Vision.

Do either support Dolby Vision?

The LG C5 does. Samsung TVs do not support Dolby Vision, and the S84H listing shows HDR only.

Which should I buy for a bright room?

The C5 is the safer pick. LG markets the evo panel as bright-room ready with an anti-glare coating. The Samsung listing gives no brightness or anti-glare figures.
