Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Zealot S97 ranks #49 of 82 large speakers by sound quality at $65.86; the Onn Medium Party Speaker Gen 2 ranks #46 of 76 boombox speakers by sound quality at $90.
The case for the Zealot S97: For a compact 3.3kg boombox, the S97 delivers unusually deep, clean-enough bass with a more sensible default balance than many inexpensive Zealot models. The tradeoff: It is not especially loud for its size, battery life is only a claimed 12 hours, and the bass preset can swamp the rest of the music.
The case for the Onn Medium Party Speaker Gen 2: Under $100 with LED lights synced to music. The catch: Lacking detail compared to the Onn Large Party Gen 2 and not as deep of bass.
Buy the Zealot S97 ($65.86) for a large speaker; the Onn Medium Party Speaker Gen 2 ($90) suits a boombox speaker instead.

The Two Speakers In Full
Zealot S97: $65.86 with coupon YZZL10 AliExpress eBay
Pros: For a compact 3.3kg boombox, the S97 delivers unusually deep, clean-enough bass with a more sensible default balance than many inexpensive Zealot models. It also brings IPX6 protection, aux and microSD playback, power-bank outputs, three EQ presets and PartyAdd linking.
Cons: It is not especially loud for its size, battery life is only a claimed 12 hours, and the bass preset can swamp the rest of the music. There is no app or fine-grained EQ, so the Vocal preset is the only practical way to improve the balance. It is still heavy for a speaker with this output ceiling.
