These are not really the same size class, and that is the honest framing here. The JBL Authentics 300 ranks #32 of 75 boombox speakers by sound quality at $299.95; the Sonos Move 2 ranks #25 of 78 large speakers by sound quality at $496.11.
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.
The case for the Sonos Move 2: Warm sounding with somewhat rolled off treble. The tradeoff: Not very loud.
Buy the JBL Authentics 300 at $299.95 if you want a boombox speaker. Buy the Sonos Move 2 at $496.11 if you want a large speaker instead.

Sonos Move 2: $496.11 Amazon eBay
Pros: Warm sounding with somewhat rolled off treble. Slightly better midrange clarity than the Move 1.
Cons: Not very loud. It may share the Move 1’s full-volume issues, though more sound samples at full volume are needed to confirm that.
