Short answer: the JBL PartyBox 100 is the better sound-first choice if you find one, while the PartyBox 330 is the current convenience choice with wheels and a handle. The older 100 is unusually neutral for the category and reaches deep, with only a small upper-midrange peak. The 330 improves transportability, but its own notes say its sound remains close to the 310 and Stage 320 despite the output increase. One note: the JBL Partybox 100 is no longer sold new, but at #8 of 39 party speakers by sound quality it still outranks most current models, so used is worth considering.
On the JBL Partybox 100 side: Quite neutral sound, pretty deep bass. The tradeoff: A slight peak in the upper mids.
The case for the JBL Partybox 330: Handle and wheels are convenient. The tradeoff: Sound quality is nearly identical to the 310 and Stage 320 despite the power bump.
One note: the JBL Partybox 100 is no longer sold new, but at #8 of 39 party speakers by sound quality it still outranks most current models, so used is worth considering.
Buy the JBL PartyBox 100 if you find one in good condition and want the more neutral, deep-bass party speaker.
Buy the JBL PartyBox 330 if wheels and a handle make the larger speaker practical for your use.
If battery life is a priority, the JBL Partybox 330 is rated for 18 hours versus 12 hours for the JBL Partybox 100.
Water resistance is not close: the JBL Partybox 330 is rated at IPX4 (splashing), well ahead of the JBL Partybox 100 at no water resistance.

Pros: Quite neutral sound, pretty deep bass. Measured bass extension of 41Hz (-10dB).
Cons: A slight peak in the upper mids. Slight TWS issue where the 2nd is slightly delayed. Just as loud and slightly deeper bass than a Stormbox Blast which is way smaller with better sound quality. Discontinued.

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.
