Short answer: the Partybox 720, and availability alone may decide it. It ranks #3 of 11 large party speakers at $899.95. The Rockster ranks #6 at €950 and, per our notes, is only available in Europe.
The Rockster’s claim to fame is being the loudest battery-powered speaker on the site, with deeper bass than the Soundboks 2 and 3. The tradeoff is real: extremely heavy and genuinely difficult to move, with no stereo mode at all.
The Partybox 720 is described in our own notes as the biggest, best-sounding speaker with a battery, and it’s not exactly convenient either: very large and heavy, with a default tuning our notes call somewhat dark until you dial in some treble boost.
Buy the Partybox 720 if you’re outside Europe or want JBL’s ecosystem and lightshow. Buy the Rockster only if you’re in Europe and specifically want the loudest option available.

JBL Partybox 720: $899.95 Amazon Bhphotovideo
Pros: Biggest best sounding speaker with a battery. Handle and wheels are convenient. Lightshow ability.
Cons: Very large and heavy. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal. Somewhat dark sounding by default, needs some treble boost to sound neutral
