Which is better for gaming, the LG 65QNED84B or the Roku Select Series 75-Inch?

The LG. It has 144Hz VRR, Motion Booster 288 and AMD FreeSync Premium. The Roku lists no VRR or FreeSync, so fast games will look less smooth.

Is the Roku Select Series 75-Inch worth it over the smaller LG?

If size matters most, yes. You get 10 more inches for $130 less at current best prices. If you watch dark HDR movies or game, the LG's Mini LED backlight and Dolby Vision are worth the extra.

Which has better picture quality?

The LG. Mini LED backlighting with local dimming produces deeper blacks and brighter highlights than the Roku's direct-lit panel. The Roku's QLED layer helps color, but it cannot match the LG's contrast.

Does the Roku Select Series 75-Inch support Dolby Vision?

No. It supports HDR10+ and HLG. The LG supports Dolby Vision, HDR10 Pro and HLG.

Neither maker publishes a lifespan figure. Both are LED-based LCD TVs, and panel life is similar. The LG's extra gaming and HDR features are more likely to feel dated than to fail.
