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 40 party speakers by sound quality at $549.95; the Tribit Stormbox Blast 2 ranks #25 of 76 boombox speakers by sound quality at $279.99.
The case for the JBL Partybox 330: A highly complete rolling party speaker: removable battery, telescoping handle and wheels, light show, Auracast, USB-C lossless and optical inputs, plus dual mic/guitar inputs. The catch: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational.
The case for the Tribit Stormbox Blast 2: Pretty deep bass. Watch for: Sounds quite muddy with the boosted lower and upper bass.
Buy the JBL Partybox 330 at $549.95 for a party speaker, or the Tribit Stormbox Blast 2 at $279.99 for a boombox speaker instead.
If battery life is a priority, the Tribit Stormbox Blast 2 is rated for 30 hours versus 18 hours for the JBL Partybox 330.
If water resistance matters to you, the Tribit Stormbox Blast 2 at IP67 (brief submersion) holds up far better than the JBL Partybox 330 at IPX4 (splashing).

The Two Speakers In Full
JBL Partybox 330: $549.95 Amazon B&H Photo Video eBay
Pros: A highly complete rolling party speaker: removable battery, telescoping handle and wheels, light show, Auracast, USB-C lossless and optical inputs, plus dual mic/guitar inputs. It supplies a little more power than the JBL Partybox 310 and JBL Partybox Stage 320, while reviewers report better midrange clarity than the older JBL Partybox 310 and the same deep party-speaker bass.
Cons: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational. JBL removed the dedicated mic gain/control knobs found on earlier models, a real drawback for frequent karaoke use. Do not upgrade from a JBL Partybox 310 or JBL Partybox Stage 320 just for the higher watt figure.

Tribit Stormbox Blast 2: $279.99 Amazon eBay
Older model: the Tribit Stormbox Blast (rated 4.5/5).
Pros: Pretty deep bass. Measured bass extension of 40Hz (-10dB).
Cons: Sounds quite muddy with the boosted lower and upper bass. Boosted treble around 6kHz. Xbass mode makes it sound even more muddy. Nowhere near as neutral and balanced as the first Blast and a big downgrade unless you only care about max volume
Setup: Try the EQ from Alan Ross at this timestamp of his video
