Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox 330 ranks #1 of 50 party speakers by sound quality at $629.95; the JBL Partybox Ultimate ranks #1 of 11 large party speakers by sound quality at $1499.95.
The case for the JBL Partybox 330: Handle and wheels are convenient. The catch: Sound quality is nearly identical to the 310 and Stage 320 despite the power bump, so probably not worth an upgrade if you already own either of those.
On the JBL Partybox Ultimate side: Absolute deepest bass of any Bluetooth speaker. Handle and wheels are convenient. Watch for: Very large and heavy. No battery.
Buy the JBL Partybox 330 at $629.95 if you want a party speaker. Buy the JBL Partybox Ultimate at $1499.95 if you want a large party speaker instead.

The Two Speakers In Full
JBL Partybox 330: $629.95 Amazon Bhphotovideo
Pros: Handle and wheels are convenient. Customizable lightshow. Removable battery. Slightly more power than the 310 and Stage 320 (280W vs 240W). Adds an optical TV input and USB-C lossless playback, plus dual mic and guitar inputs for karaoke and live sets.
Cons: Sound quality is nearly identical to the 310 and Stage 320 despite the power bump, so probably not worth an upgrade if you already own either of those. Removed the dedicated mic gain and microphone control knobs found on the 310/320. Some people don’t like the new lightshow design. Very large. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.
