Short answer: the JBL Boombox 3. It ranks #24 of 76 boombox speakers by sound quality, rated 3.8/5, at $399; the Bumpboxx Flare 8 ranks #58, rated 2.6/5, and costs $400, which makes this an easy call rather than a real tradeoff.
The case for the JBL Boombox 3: IP67 rated. The tradeoff: Dips in mid bass range which makes the bass sound undefined, bass boosted, peaky at 700Hz, not quite as good mids and treble as the Blast.
Why pick the Bumpboxx Flare 8: A retro-styled, 8.6kg party speaker with useful real-world features: IPX6 splash resistance, FM radio, USB and microSD playback, aux input, TWS pairing and a claimed 118dB maximum output. Watch for: Bass is thuddy rather than deep or controlled, and there is no app to improve the tuning.
Buy the JBL Boombox 3. It is rated higher for sound quality than the Bumpboxx Flare 8 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
There is a real battery-life gap here: the JBL Boombox 3 is rated for 24 hours, the Bumpboxx Flare 8 only 12 hours.

Bumpboxx Flare 8: $400 Bumpboxx eBay
Pros: A retro-styled, 8.6kg party speaker with useful real-world features: IPX6 splash resistance, FM radio, USB and microSD playback, aux input, TWS pairing and a claimed 118dB maximum output. It can play much louder than compact Bluetooth speakers and is easy to aim at a small outdoor gathering.
Cons: Bass is thuddy rather than deep or controlled, and there is no app to improve the tuning. Owner reports also raise reliability concerns, including noisy or intermittent volume controls and sound cutting out at high volume. It is a fun-looking niche product, not a sound-quality or durability leader.
