Short answer: the Onn Large Party gen 2 is the value play; the JBL Partybox 330 is the safer sound. The Onn is called an insane value speaker at $129, though it is not quite as loud as the old one. The 330 has a convenient handle and wheels, but its sound quality is nearly identical to the 310 and Stage 320 despite the power bump.
Buy the JBL Partybox 330 if sound quality matters more than the price. Buy the Onn Large Party gen 2 if the price matters more than sound quality.
There is a real battery-life gap here: the JBL Partybox 330 is rated for 18 hours, the Onn Large Party gen 2 only 12 hours.
