Short answer: the JBL Partybox 330, unless price is everything. The Rockville Rock Party 6 is cheap, but it has no deep bass and slightly harsh upper mids. The 330 has a convenient handle and wheels, though its sound quality is nearly identical to the 310 and Stage 320 despite the power bump.
Buy the JBL Partybox 330. It is rated higher for sound quality, and the $530 you would save on the Rockville Rock Party 6 does not close the gap.
There is a real battery-life gap here: the JBL Partybox 330 is rated for 18 hours, the Rockville Rock Party 6 only 6 hours.
If water resistance matters to you, the JBL Partybox 330 at IPX4 (splashing) holds up far better than the Rockville Rock Party 6 at no water resistance.

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.
