These sit in different size classes, so this is not a straight ranking comparison. The Bose S1 Pro+ ranks #6 of 16 battery-powered PA speakers by sound quality at $699; the Sony GTK-XB90 ranks #42 of 46 party speakers by sound quality at $429.
What the Bose S1 Pro+ does well: Extremely compact and light with flexible placement options, and very loud for its size. It has an adjustable EQ, which the Sony GTK-XB90 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 Sony GTK-XB90 is the longer-running pick. Deep punchy EXTRA BASS technology for party use. It is rated for 16 hours of battery against 11 for the Bose S1 Pro+. It supports LDAC Bluetooth, which the Bose S1 Pro+ lacks. It plays in stereo from a single unit, unlike the Bose S1 Pro+. The tradeoff: Bass is muddy and not deep, weird midrange peak, rolled off treble and overall strange tuning.
Worth knowing: the Sony GTK-XB90 has been discontinued and is hard to find new at this point.
Buy the Bose S1 Pro+ at $699 if you want a battery-powered PA speaker. Buy the Sony GTK-XB90 at $429 if you want a party speaker instead.

The Two Speakers In Full
Bose S1 Pro+: $699.00 Amazon $699.00 eBay
Older model: the Bose S1 Pro (ranked lower, rated 4/5). See every Bose S1 Pro generation.
Pros: Extremely compact and light with flexible placement options, and very loud for its size. 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. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage. Measured bass extension of 62Hz (-3dB).
Cons: Leans toward a bright sound signature, and its bass bottoms out as the volume rises, so full range music suffers well before maximum loudness. Better suited for voice and instrument amplification than for casual music listening. 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.
