Short answer: the JBL Partybox 330 for larger music-led gatherings, with the Bose S1 Pro+ reserved for portable PA duties. The JBL ranks #2 of 49 party speakers at $599.95; the Bose ranks #6 at $699, so the price gap is only $99.05.
The Partybox 330 is built to cover more ground. Its wheels, telescoping handle, removable battery, 18-hour rated battery life, USB-C lossless audio, optical input, and dual mic or guitar inputs suit a serious party setup. Reviews report better midrange clarity than the older Partybox 310 and similarly deep bass, though the improvement over the 310 or Stage 320 is modest and dedicated mic gain controls have been removed.
The S1 Pro+ makes sense when the source mix matters as much as the music. At 14.3 lbs (6.5 kg) it is far easier to carry, and its three-channel mixer, two combo inputs, orientation-aware EQ, and optional wireless transmitters support performers and presenters. It cannot match the JBL’s scale for full-range music, where it gets distorted above about two-thirds volume, and it lacks water resistance.
Buy the JBL Partybox 330 for the top ranking, higher-output party format, longer battery rating, and rolling portability at a lower current price.
Buy the Bose S1 Pro+ if compact carry weight and its flexible mixer and XLR or instrument connectivity outweigh the need for party-speaker output.
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.

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