Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox 330 ranks #2 of 53 party speakers by sound quality at $629.95; the Zealot ZE41 ranks #17 of 113 boombox speakers by sound quality at $219.95.
The JBL Partybox 330 is the longer-running pick. A rolling party speaker with deep bass, a removable battery, a light show and inputs for mics and a guitar. It is rated for 18 hours of battery against 4 for the Zealot ZE41. The tradeoff: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational.
The Zealot ZE41 is the lighter pick. A huge boombox with lots of bass, volume and play time for the money. At 25.3 lbs (11.48 kg) it weighs noticeably less than the JBL Partybox 330 at 37.7 lbs (17.1 kg). Watch for: The heaviest and biggest boombox speaker around.
