Short answer: the Ruimatech RM-10. It ranks #28 of 89 boombox speakers by sound quality, rated 3.8/5, at $159.99; the JBL Authentics 300 ranks #40, rated 3.5/5, and costs $299.95, so there is little reason to consider the other one.
The case for the Ruimatech RM-10: A three-way boombox (80W woofer, two 20W midranges, two 10W tweeters and dual passive radiators, 140W RMS) with a hi-fi leaning clarity, highs that don’t get screechy at max volume, and bass that holds on at full volume. The tradeoff: It is tuned bass boosted, much like the JBL Boombox 3.
What the JBL Authentics 300 does well: Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). The tradeoff: Narrow sounding, bass not as deep as others.
Buy the Ruimatech RM-10. It is rated higher for sound quality than the JBL Authentics 300 and costs less, which makes it the one to get unless you need something the other one does better.
If battery life is a priority, the Ruimatech RM-10 is rated for 14 hours versus 8 hours for the JBL Authentics 300.
If water resistance matters to you, the Ruimatech RM-10 at IPX6 (powerful water jets) holds up far better than the JBL Authentics 300 at no water resistance.

Ruimatech RM-10: $159.99 Amazon eBay
Pros: A three-way boombox (80W woofer, two 20W midranges, two 10W tweeters and dual passive radiators, 140W RMS) with a hi-fi leaning clarity, highs that don’t get screechy at max volume, and bass that holds on at full volume. Side by side it beat the W-King X20S and X20 and sounded as good as the Tribit Stormbox Blast 2, especially at higher volume. IPX6, a claimed 14 hours, a USB-C power bank, 30W fast charging and stereo pairing.
Cons: It is tuned bass boosted, much like the JBL Boombox 3. There is no app or custom EQ and no shoulder strap, and the design is plain.
