Short answer: the JBL Partybox 300 for sound, the Bose S1 Pro+ for portability. The S1 Pro+ is extremely compact and light with flexible placement options, but with full range music it distorts above two-thirds volume. The JBL pairs exceptional sound quality, crisp crystal clear highs and midranges and hard punchy bass without muddiness with the downside of being hard to carry, too tall and prone to dragging on the ground. The JBL Partybox 300 is discontinued; its replacement is the JBL Partybox 330.
Buy the JBL Partybox 300 at $300 for a party speaker, or the Bose S1 Pro+ at $699 for a battery-powered PA speaker instead.
There is a real battery-life gap here: the JBL Partybox 300 is rated for 18 hours, the Bose S1 Pro+ only 11 hours.
