Which has the better picture?

The LG's Mini LED backlight gives finer local dimming and deeper blacks. The Toshiba adds Dolby Vision and HDR10+ Adaptive, which help more with streaming content. It is close, but the LG wins on panel technology.

Which is better for gaming?

The Toshiba. It lists Game Mode with ALLM, VRR and eARC, which the LG does not. Both are 60 Hz panels, so neither suits high-frame-rate console play.

Is the LG worth the extra $69?

Only if you want a smaller screen or prefer webOS and Google Assistant. Otherwise the Toshiba gives you a much larger QLED screen for less money.

Neither maker publishes a lifespan figure for these models, and both are LED-backlit sets with similar build. Buy on warranty and store return policy rather than expected life.

Do both support Dolby Atmos?

The Toshiba lists Dolby Atmos and REGZA Power Audio. The LG listing does not mention Dolby Atmos, so assume standard stereo sound.
