Short answer: the JBL Partybox 330. It ranks #1 of 51 party speakers by sound quality at $629.95; the Bose S1 Pro+ ranks #16 and costs $699, so there is little reason to consider the other one.
The case for the Bose S1 Pro: Extremely compact and light with flexible placement options. The catch: With full range music, it becomes distorted above ⅔ volume.
What the JBL Partybox 330 gets right: Handle and wheels are convenient. The catch: Sound quality is nearly identical to the 310 and Stage 320 despite the power bump.
Buy the JBL Partybox 330. It ranks higher for sound quality than the Bose S1 Pro+ and costs less, so the other one has nothing left to offer.
Battery life favors the JBL Partybox 330: rated for 18 hours against 11 hours for the Bose S1 Pro+.
There is a real gap in water resistance: the JBL Partybox 330 at IPX4 (splashing) against the Bose S1 Pro+, which has no water resistance.

The Two Speakers In Full
Bose S1 Pro+: $699.00 Amazon eBay
Pros: Extremely compact and light with flexible placement options. Full sound with no lack of low-end output, crystal-clear audio quality. Three-channel mixer (2 XLR/quarter-inch combo mic-instrument + 1 line/Bluetooth), each with its own OLED display for quick treble/bass/reverb adjustment. Auto EQ adjusts sound based on orientation. Multiple angled surfaces for various positioning including tilted portrait mode, plus a line out to daisy-chain a second unit. Optional WT-XLR/WT-INST wireless transmitters dock, pair, and charge right in the speaker for a cable-free mic or instrument. Up to 11 hours battery life. Professional build quality. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage.
Cons: With full range music, it becomes distorted above ⅔ volume, and reviewers describe it as screeching at max volume. Better suited for voice amplification. Not as much deep bass as the Everse 8, midrange sounds reasonably balanced. Treble is pretty boosted. Not stereo. Designed for more loudness than deeper bass. Ports are fully exposed with no water resistance. Charges via a less common three-prong AC cable instead of the two-prong barrel cable most rivals use.

JBL Partybox 330: $629.95 Amazon B&H Photo Video eBay
Pros: Handle and wheels are convenient. Customizable lightshow. Removable battery. Slightly more power than the 310 and Stage 320 (280W vs 240W). Adds an optical TV input and USB-C lossless playback, plus dual mic and guitar inputs for karaoke and live sets.
Cons: Sound quality is nearly identical to the 310 and Stage 320 despite the power bump, so probably not worth an upgrade if you already own either of those. Removed the dedicated mic gain and microphone control knobs found on the 310/320. Some people don’t like the new lightshow design. Very large.
