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 53 party speakers by sound quality at $629.95; the JBL Partybox Encore Essential 2 ranks #6 of 113 boombox speakers by sound quality at $249.95.
What the JBL Partybox 330 does well: A rolling party speaker with deep bass, a removable battery, a light show and inputs for mics and a guitar. The tradeoff: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational.
The JBL Partybox Encore Essential 2 is the lighter option. A compact party speaker with balanced sound, punchy bass, mic and guitar inputs, and enough volume for a backyard party. At 13.7 lbs (6.2 kg) it weighs much less than the JBL Partybox 330 at 37.7 lbs (17.1 kg). The tradeoff: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume.
Buy the JBL Partybox 330 ($629.95) for a party speaker; the JBL Partybox Encore Essential 2 ($249.95) suits a boombox speaker instead.
