These are not really the same size class, and that is the honest framing here. The Bose S1 Pro+ ranks #6 of 16 battery-powered PA speakers by sound quality at $699; the Audiocase S5 ranks #27 of 49 party speakers by sound quality at $645.

Why pick the Bose S1 Pro+: Extremely compact and light with flexible placement options, and very loud for its size. It has an adjustable EQ, which the Audiocase S5 lacks. The catch: Leans toward a bright sound signature, and its bass bottoms out as the volume rises, so full range music suffers well before maximum loudness.
The Audiocase S5 is the longer-running pick. A 17.4 lbs (7.9 kg) stereo boombox with 2x 5” woofers, a 1” tweeter, a claimed 30-hour removable battery and up to 108dB of output. It is rated for 30 hours of battery against 11 for the Bose S1 Pro+. It supports aptX Bluetooth, which the Bose S1 Pro+ lacks. It plays in stereo from a single unit, unlike the Bose S1 Pro+.
Worth knowing: the Audiocase S5 has been discontinued and is hard to find new at this point.
Buy the Bose S1 Pro+ at $699 for a battery-powered PA speaker, or the Audiocase S5 at $645 for a party speaker instead.
