Which is better for a bright living room?

The Samsung S90H. Its Glare Free coating cuts reflections, which matters in rooms with windows or overhead lights. The LG C6 is brighter but does not list an anti-glare coating.

Is the LG C6 worth the extra $500?

If you want 65 inches, yes. The C6 adds 23 inches of screen, Dolby Vision and a brighter evo panel. If 42 inches fits your room, the S90H saves you about $500.

Which is better for gaming?

The Samsung S90H lists up to 165Hz with VRR and G-SYNC compatibility. The LG C6 runs 120Hz but adds FreeSync Premium and a 0.1ms response time. Both are strong; the Samsung has the higher refresh ceiling.

Does either support Dolby Vision?

Only the LG C6. The Samsung S90H lists HDR support but no Dolby Vision, so Dolby Vision content plays in a standard HDR format on it.

Which has better voice assistant support?

They differ by ecosystem. The Samsung S90H works with Amazon Alexa and Google Assistant. The LG C6 works with Google Assistant and Siri, and its webOS platform adds Google Gemini and Microsoft Copilot.

Which is easier to place in a room?

The Samsung S90H at 18.3 lb and 42 inches is far easier to move and mount. The LG C6 weighs 31 lb at 65 inches and needs a wider wall or stand.
