Which is better for a bright living room?

The QM8K. Its anti-reflective panel and much higher peak brightness hold up better against windows and lamps. The QM6K is bright for its price but has no anti-glare claim.

Is the QM8K worth $500 more than the QM6K?

If you game at high frame rates, watch a lot of HDR, or fight glare, yes. If you mainly want the largest screen for movies and sports, the QM6K covers that for less.

Which is better for gaming?

Both run 144Hz. The QM8K adds Game Accelerator up to 288 VRR and better halo control, so it edges ahead. The QM6K is still a strong budget gaming set per reviewers.

How much bigger is the 75-inch QM6K?

About 10 inches diagonally, roughly 18% more screen area than the 65-inch QM8K. That matters most if you sit more than 8 feet away.

Which has better sound out of the box?

The QM8K, with Bang & Olufsen tuning and Dolby Atmos. The QM6K uses standard speakers, so budget for a soundbar.

Do both have Google TV?

Yes, both are Google TV smart TVs with Netflix and YouTube. Reviewers note some menu lag on the QM6K.
