Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Onn Medium Party Speaker Gen 2 ranks #65 of 113 boombox speakers by sound quality at $90; the Zealot S67 ranks #118 of 120 large speakers by sound quality at $70.94.
What the Onn Medium Party Speaker Gen 2 does well: An affordable waterproof party speaker with a big woofer, lights, a karaoke mic input and FM radio. It links with other speakers (Party Sync Mode), which the Zealot S67 cannot. The tradeoff: Lacking detail compared to the Onn Large Party gen 2 and not as deep of bass.
The Zealot S67 is the lighter choice. A budget waterproof speaker with a long rated battery, USB-C charging, microSD playback, and stereo pairing. At 5.3 lbs (2.4 kg) it weighs much less than the Onn Medium Party Speaker Gen 2 at 11 lbs (5 kg). It plays in stereo from a single unit, unlike the Onn Medium Party Speaker Gen 2. The catch: Sound quality is the catch.
Buy the Onn Medium Party Speaker Gen 2 at $90 if you want a boombox speaker. Buy the Zealot S67 at $70.94 if you want a large speaker instead.
