Short answer: the Yeahbox Sonic Boom Max 3. It ranks #57 of 98 boombox speakers by sound quality, rated 3.2/5, at $228.99; the JBL PartyBox On-the-Go Essential ranks #66, rated 3.0/5, and costs $279.95, so there is not much of a tradeoff to weigh.
The JBL PartyBox On-the-Go Essential is the lighter choice. Includes a wireless microphone plus wired mic and guitar inputs with echo, bass and treble controls for karaoke. At 13.4 lbs (6.1 kg) it weighs noticeably less than the Yeahbox Sonic Boom Max 3 at 16.8 lbs (7.64 kg). The tradeoff: No measurements, so its rating is estimated; it is essentially the JBL Partybox On the Go without app support.
The Yeahbox Sonic Boom Max 3 is the tougher choice. A large 3-way, 5-driver party speaker with claimed 200W RMS output, a 111Wh battery, USB-C fast charging, app EQ, TWS pairing, and aux, USB and microSD playback. It is rated IPX6 against IPX4 for the JBL PartyBox On-the-Go Essential. It has an adjustable EQ, which the JBL PartyBox On-the-Go Essential lacks. The tradeoff: There is limited independent testing and the water/dust rating is reported inconsistently across listings.
Buy the Yeahbox Sonic Boom Max 3. It is rated higher for sound quality than the JBL PartyBox On-the-Go Essential and costs less, which makes it the one to get unless you need something the other one does better.

JBL PartyBox On-the-Go Essential: $279.95 Estimated Amazon $279.95 eBay

Yeahbox Sonic Boom Max 3: $228.99 Amazon $228.99 eBay
Pros: A large 3-way, 5-driver party speaker with claimed 200W RMS output, a 111Wh battery, USB-C fast charging, app EQ, TWS pairing, and aux, USB and microSD playback. Listener comparisons describe powerful bass, strong output and decent mids and highs for outdoor party use.
Cons: There is limited independent testing and the water/dust rating is reported inconsistently across listings. Listener comparisons find it less clear and refined than stronger boombox rivals, so its big bass and output are a better fit for parties than critical listening.
