Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Google Nest Audio ranks #9 of 15 powered desktop speakers by sound quality at $99.99; the JBL Authentics 300 ranks #46 of 112 boombox speakers by sound quality at $299.95.

Why pick the Google Nest Audio: An affordable Google Assistant speaker with Chromecast casting and respectable bass from one small box. It supports AAC Bluetooth, which the JBL Authentics 300 lacks. The tradeoff: Each unit is mono; a genuine left-right stereo pair means buying two and pairing them over Wi-Fi.
The JBL Authentics 300 is the battery-powered option. A retro styled smart speaker with both Alexa and Google Assistant, a leather handle and battery power. Its battery is rated for 8 hours, while the Google Nest Audio needs an outlet. Watch for: Narrow sounding, bass not as deep as others.
One note: the Google Nest Audio is discontinued and no longer widely available new. The Google Nest Audio’s replacement, the Google Home Speaker, is rated 3.0/5 at $99.99.
Buy the Google Nest Audio at $99.99 if you want a powered desktop speaker. Buy the JBL Authentics 300 at $299.95 if you want a boombox speaker instead.
