Short answer: the Partybox 520, if the budget stretches that far. It ranks #5 of 11 large party speakers at $799.95; the T12 ranks #10 at $379.04, $421 less.
The T12’s own review is modest: relatively cheap for what you get, not a bad speaker for the price. Its cons describe a boxy sound lacking the clarity of the higher-ranked speakers in the class.
The Partybox 520 is JBL’s biggest battery-powered speaker currently made, with the same handle, wheels, and lightshow the rest of the Partybox line offers.
Buy the Partybox 520 for the flagship experience if budget allows. Buy the T12 for a genuinely large party speaker at less than half the price.

Pros: Handle and wheels are convenient. Lightshow ability. The biggest battery powered JBL currently.
Cons: Very large and heavy. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.
