Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Google Nest Audio ranks #4 of 9 powered desktop speakers by sound quality at $99.99; the JBL Authentics 300 ranks #32 of 75 boombox speakers by sound quality at $299.95.
The case for the Google Nest Audio: Google Assistant is built in at no extra cost, and Chromecast lets you cast from almost any music app over Wi-Fi rather than only Bluetooth. The tradeoff: Each unit is mono; a genuine left-right stereo pair means buying two and pairing them over Wi-Fi.
The case for the JBL Authentics 300: Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). The tradeoff: Narrow sounding, bass not as deep as others.
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.

The Two Speakers In Full
Google Nest Audio: $99.99 each Discontinued Amazon eBay
Pros: Google Assistant is built in at no extra cost, and Chromecast lets you cast from almost any music app over Wi-Fi rather than only Bluetooth. Audio Science Review’s Klippel measurements put bass at 50Hz at -6dB and 60.4Hz at -3dB, respectable output for a single 75mm woofer at this price, and the predicted in-room response is unusually smooth for a compact single-box speaker. The Google Home app includes a two-band bass and treble EQ. Measured bass extension of 60.4Hz (-3dB).
Cons: Each unit is mono; a genuine left-right stereo pair means buying two and pairing them over Wi-Fi. On-axis measurements show more unevenness than a dedicated monitor, an average deviation of 0.569dB against roughly a tenth of that on the most neutral speakers measured this way. There is no 3.5mm or other analog input at all, no battery, and no IP rating, so it needs a stable Wi-Fi connection and a permanent outlet to work at its best. Discontinued.
