Short answer: the JBL PartyBox 330 is the right choice for a full-size party setup, while the Soundcore Boom 2 is the more portable budget-friendly option. JBL ranks 2 of 44, and Soundcore ranks 10 of 102.
The PartyBox 330 has the wheeled format for events and delivers much more scale, though its sound is close to the older PartyBox 310 and Stage 320 despite the extra power. The Boom 2 supplies deep bass for its smaller size and fun radiator lighting, but only its tweeters provide a stereo effect because it has one midrange driver.
Buy the JBL PartyBox 330 if you need a larger event speaker with wheels and party-speaker scale.
Buy the Soundcore Boom 2 if you want a much more portable speaker with strong bass for its size.
If water resistance matters to you, the Soundcore Boom 2 at IPX7 (brief submersion) holds up far better than the JBL Partybox 330 at IPX4 (splashing).

The Two Speakers In Full
JBL Partybox 330: $629.95 Amazon B&H Photo Video eBay
Older models: the JBL Partybox Stage 320 (ranked lower, rated 4.6/5), the JBL Partybox 310 (ranked lower, rated 4.5/5) and the JBL Partybox 300 (ranked lower, rated 4.3/5).
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.

Soundcore Boom 2: $99.99 Amazon B&H Photo Video eBay
Older model: the Soundcore Motion Boom (ranked lower, rated 4.5/5).
Larger model: the Soundcore Boom 2 Plus (rated 3.6/5).
Pros: Pretty deep bass for the size. Cool lights in the side passive radiators. For the best sound quality use Oluv’s EQ or Alan Ross’s EQ. With the stock tuning, this speaker would rank around #24, due to the boosted bass and rising treble. Measured bass extension of 47Hz (-10dB).
Cons: Only a single midrange driver, so you only get stereo for the tweeters. Sound processing issues with inconsistent bass notes that disappear at low levels like the Soundcore Boom and Soundcore Boost, not great for listening at low levels. Quite bass heavy with BassUp turned on, which is best left off. A little bit of a bright tuning in the treble, about +5db.
