Which is better for Dolby Atmos?

The 7.1.4 bar has rear up-firing height speakers, so it can place sound above and behind you. The S90TR has three up-firing speakers and wireless rears but no rear height layer. In a large room the 7.1.4 bar has the edge; in a normal room the S90TR is close and easier to set up.

Which is easier to set up?

The S90TR. Its rear speakers are truly wireless and need only a power outlet, and WOWCAST links it to an LG TV without a cable. The 7.1.4 bar also has wireless rears but is a larger, heavier system.

Is the 7.1.4 bar worth the extra?

It was actually cheaper at its lowest: $677.95 on October 31 versus $779.99 to $799.99 for the S90TR. The extra buys rear height channels, 100 W more power and Google Assistant, but you give up the better buyer rating and a narrower bar.

Which one fits my TV stand?

Measure first. The S90TR is 1250 mm wide; the 7.1.4 bar is 1443 mm. Both are 63 mm tall, so either can sit in front of most TVs without blocking the screen.

Which has better smart features?

The 7.1.4 bar has Google Assistant, Chromecast built-in and Wi-Fi. The S90TR focuses on LG TV integration: WOWCAST, WOW Orchestra and AI room calibration.

Neither maker publishes a lifespan figure. The S90TR carries a 1-year LG warranty, and its higher rating from more buyers is the better signal on long-term satisfaction.
