Short answer: the XDOBO Wow Max. It ranks #21 of 91 boombox speakers by sound quality, rated 3.9/5, at $206.09; the JBL Authentics 300 ranks #41, rated 3.5/5, and costs $299.95, so there is not much of a tradeoff to weigh.
The XDOBO Wow Max is the better-sounding option. Big, loud and bass-heavy, with an eight-driver, 300W layout and bass rated down to 32Hz. The tradeoff: At low and mid volume the JBL Boombox 4 sounds better in the mids and highs; the Wow Max comes across slightly muted and bass forward there, with its midrange not aimed at ear level.
The JBL Authentics 300 is the lighter option. Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). At 10.8 lbs (4.9 kg) it weighs noticeably less than the XDOBO Wow Max at 15.4 lbs (7 kg). The tradeoff: Narrow sounding, bass not as deep as others.
Buy the XDOBO Wow Max. It is rated higher for sound quality than the JBL Authentics 300 and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
XDOBO Wow Max: $206.09 Amazon eBay
Pros: Big, loud and bass-heavy, with an eight-driver, 300W layout and bass rated down to 32Hz. In side by side tests it sounded better balanced and clearer than the Zealot ZE21, with smooth mids and punchy yet deep bass, handled high volume better than the JBL Boombox 4, which gets screechy and drops bass at max, and clearly beat the Sony ULT Field 7 and W-King X20. Two wireless microphones are included, and it charges over USB-C at up to 20V.
Cons: At low and mid volume the JBL Boombox 4 sounds better in the mids and highs; the Wow Max comes across slightly muted and bass forward there, with its midrange not aimed at ear level. About 7 kg, and only a claimed 8 hours of battery.
