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 ranks #27 of 78 large speakers by sound quality at $299.95.
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: A well-integrated Sonos portable that combines Wi-Fi multiroom playback, Bluetooth, automatic Trueplay room tuning and a charging base in a sturdy carryable enclosure. The tradeoff: It is mono, heavy and less portable than a conventional Bluetooth speaker, while bass pumping and compression become audible at high volume.
Buy the JBL Authentics 300 at $299.95 if you want a boombox speaker. Buy the Sonos Move at $299.95 if you want a large speaker instead.
Water resistance is not close: the Sonos Move is rated at IP56 (powerful water jets), well ahead of the JBL Authentics 300 at no water resistance.

Sonos Move: $299.95 Discontinued Amazon eBay
Pros: A well-integrated Sonos portable that combines Wi-Fi multiroom playback, Bluetooth, automatic Trueplay room tuning and a charging base in a sturdy carryable enclosure. Reviews praise its broad, full-bodied sound, warm tonal balance and weightier bass than smaller Sonos speakers, particularly at normal indoor listening levels. Measured bass extension of 49Hz (-10dB).
Cons: It is mono, heavy and less portable than a conventional Bluetooth speaker, while bass pumping and compression become audible at high volume. Deep bass and maximum output trail the strongest speakers in its size class, and the rolled-off treble sacrifices some air and detail. It is discontinued in favor of Move 2, so buy used with battery condition in mind. Discontinued.
