Short answer: the Zealot S95. It ranks #37 of 113 boombox speakers by sound quality, rated 3.7/5, at $157.41; the Onn Pro X Large Boom Boombox ranks #49, rated 3.4/5, and costs $199, which makes this an easy call rather than a real tradeoff.
The Zealot S95 is the better-sounding, lighter pick. An affordable stereo boombox with water resistance, a power bank output and linking for up to 100 speakers. At 11.3 lbs (5.11 kg) it weighs noticeably less than the Onn Pro X Large Boom Boombox at 17.2 lbs (7.8 kg). Watch for: A little rolled off up top and not that balanced through the rest of the range.
The Onn Pro X Large Boom Boombox is the longer-running choice. A powerful, waterproof party boombox with a 20 hour battery and light modes at a low price. It is rated for 20 hours of battery against 12 for the Zealot S95. Watch for: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.
Buy the Zealot S95. It is rated higher for sound quality than the Onn Pro X Large Boom Boombox and costs less, so only choose the other one for a particular feature it does better.
