Short answer: the JBL Boombox 4 for quality; the Bumpboxx Flare 6 for a loud party box. The JBL has pretty insane output for its size with a 7-band EQ, but it is overpriced, sounds worse than the Boombox 3 out of the box and drops the aux input. The Flare 6 can get pretty loud, but its bass is not deep and is thuddy.
Buy the JBL Boombox 4. It is rated higher for sound quality and still sold new, while the Bumpboxx Flare 6 is discontinued.
There is a real battery-life gap here: the JBL Boombox 4 is rated for 28 hours, the Bumpboxx Flare 6 only 12 hours.

JBL Boombox 4: $549.95 Amazon B&H Photo Video eBay
Older models: the JBL Boombox 3 (ranked lower, rated 3.8/5), the JBL Boombox 2 (ranked lower, rated 3.5/5) and the JBL Boombox (ranked lower, rated 2.9/5).
Pros: Pretty insane output capability for the size. IP68 protection and Auracast pairing with other current JBL speakers. Measured bass extension of 41Hz (-10dB).
Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.
