Short answer: the JBL Partybox 330 for detail. It is the top-ranked party speaker here, with a removable battery, a handle and wheels, and dual mic and guitar inputs, though it is very large and its PartyBoost/Auracast daisychain only works with other JBL speakers. The W-King T9 Pro costs less than half as much and has a removable battery of its own, but it sounds warm and somewhat gritty and is well behind the 330 on detail.
Buy the JBL Partybox 330. It is rated higher for sound quality, and saving $458.46 with the W-King T9 Pro does not make up for the sound-quality gap.
There is a real battery-life gap here: the JBL Partybox 330 is rated for 18 hours, the W-King T9 Pro only 12 hours.
Water resistance is not close: the JBL Partybox 330 is rated at IPX4 (splashing), well ahead of the W-King T9 Pro at no water resistance.
