Short answer: the JBL Partybox Stage 320 for better sound quality, the Zealot PT21 for the lower price. The JBL Partybox Stage 320 ranks #2 of 50 party speakers at $629.95. The Zealot PT21 ranks #15 at $216.73, $413.22 cheaper.
What the JBL Partybox Stage 320 offers: Handle and wheels are convenient. Watch for: Slightly sibilant in the treble at full blast.
On the Zealot PT21 side: 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. Set against that: 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.
Buy the JBL Partybox Stage 320 if sound quality matters more than the price. Buy the Zealot PT21 if the price matters more than sound quality.

Pros: Handle and wheels are convenient. Customizable color lighting modes. Keeps more bass than the 310 at high volume. Removable battery.
Cons: Slightly sibilant in the treble at full blast. Very large. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.

Zealot PT21: $216.73 Aliexpress
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.
