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.
What the JBL Partybox 330 gets right: Handle and wheels are convenient. The tradeoff: Sound quality is nearly identical to the 310 and Stage 320 despite the power bump.
On the Onn Large Party gen 2 side: An insane value speaker. The catch: Not quite as loud as the old one.
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.

The Two Speakers In Full
JBL Partybox 330: $549.95 Amazon B&H Photo Video eBay
Pros: A highly complete rolling party speaker: removable battery, telescoping handle and wheels, light show, Auracast, USB-C lossless and optical inputs, plus dual mic/guitar inputs. It supplies a little more power than the JBL Partybox 310 and JBL Partybox Stage 320, while reviewers report better midrange clarity than the older JBL Partybox 310 and the same deep party-speaker bass.
Cons: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational. JBL removed the dedicated mic gain/control knobs found on earlier models, a real drawback for frequent karaoke use. Do not upgrade from a JBL Partybox 310 or JBL Partybox Stage 320 just for the higher watt figure.

Onn Large Party gen 2: $129 Walmart eBay
Pros: A remarkably full-featured, manageable 9.5kg party speaker: wheels and handle, FM radio, aux, USB-A charging, mic and guitar inputs with karaoke echo, and Party Sync. Independent testing confirms bass with real impact and enough output for a large room; it is a clear improvement over the Gen 1 for low-end weight.
Cons: The low price shows in the refinement. Consumer Reports found boomy bass, hazy/grainy mids, a prominent smeared treble and a narrow, two-dimensional soundfield; it also notes distortion or other audio issues. There is no app or EQ to tame the tuning, and IPX4 only covers splashes rather than rain or immersion.
