Short answer: the Zealot PT21. It ranks #12 of 43 party speakers by sound quality, rated 4.1/5, at $225.86. The Onn Large Party gen 1 ranks #32, rated 2.7/5, at $100, $125.86 cheaper, which does not close the gap in sound quality.
What the Zealot PT21 does well: Dual 166mm woofers and 200W output in a lighter, more compact body than the ZE41, with a bundled wireless microphone and echo effect built in for karaoke. The tradeoff: Unlike some other Zealot models, app-based EQ customization doesn’t appear to be fully supported yet, and IPX5 means it can handle splashes but not submersion.
Why pick the Onn Large Party gen 1: A genuinely useful feature set for a compact party speaker: FM radio, 3.5mm aux, USB-A phone charging, a mic/guitar input, lights, and Party Sync pairing. Watch for: Sound is not a strong reason to seek one out.
One note: the Onn Large Party gen 1 is discontinued and no longer widely available new.
Buy the Zealot PT21. It is rated higher for sound quality, and the $125.86 you would save on the Onn Large Party gen 1 does not close the gap.
There is a real gap in water resistance: the Zealot PT21 at IPX5 (water jets) against the Onn Large Party gen 1, which has no water resistance.

Zealot PT21: $216.73 AliExpress eBay
Pros: Dual 166mm woofers and 200W output in a lighter, more compact body than the ZE41, with a bundled wireless microphone and echo effect built in for karaoke. Quite deep bass for the price, even deeper than the JBL Boombox 4 in direct comparisons.
Cons: Unlike some other Zealot models, app-based EQ customization doesn’t appear to be fully supported yet, and IPX5 means it can handle splashes but not submersion.

Onn Large Party gen 1: $100 Discontinued eBay
Newer model: the Onn Large Party gen 2, ranked higher, rated 3.9/5.
Pros: A genuinely useful feature set for a compact party speaker: FM radio, 3.5mm aux, USB-A phone charging, a mic/guitar input, lights, and Party Sync pairing. Its rolling 10.5kg cabinet, carry handle and claimed 13-hour battery make it easy to take to casual outdoor gatherings, and it can play louder than a typical small Bluetooth speaker. Measured bass extension of ~60Hz (-10dB).
Cons: Sound is not a strong reason to seek one out. Reviewer comparisons find limited deep bass (about 60Hz at -10dB), uneven mids and a boxy, strained presentation at high volume. It has no app or EQ, no water rating, and is discontinued; the newer Onn Large Party gen 2 is the more sensible choice when available.
