Short answer: the Soundcore Boom 2 Plus. It ranks #39 of 113 boombox speakers by sound quality, rated 3.6/5, at $169.99; 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 Soundcore Boom 2 Plus is the lighter pick. A fairly light stereo boombox, easy to carry to the beach or park. At 8.4 lbs (3.8 kg) it weighs much less than the Onn Pro X Large Boom Boombox at 17.2 lbs (7.8 kg). Watch for: Warm tuning meaning a rolled off treble and some upper bass boost.
What the Onn Pro X Large Boom Boombox does well: A powerful, waterproof party boombox with a 20 hour battery and light modes at a low price. Watch for: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.
Buy the Soundcore Boom 2 Plus. It is rated higher for sound quality than the Onn Pro X Large Boom Boombox and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
