Short answer: the LG XL7 if you need to move it, the Bose S1 Pro+ if you need it small. The XL7 adds wheels and a handle but has recessed treble and bass that is not as deep as a Partybox 310. The S1 Pro+ is extremely compact and light with flexible placement options, though full range music makes it distort above two-thirds volume.

Buy the Bose S1 Pro+ at $699 if you want a battery-powered PA speaker. Buy the LG XL7 at $496.19 if you want a party speaker instead.
Battery life favors the LG XL7: rated for 20 hours against 11 hours for the Bose S1 Pro+.
Water resistance is not close: the LG XL7 is rated at IPX4 (splashing), well ahead of the Bose S1 Pro+ at no water resistance.

Extremely compact and light with flexible placement options, and very loud for its size.
