Short answer: the Soundcore Rave 3/3s. It ranks #20 of 50 party speakers by sound quality at $299.99; the Sony GTK-XB90 ranks #46 and costs $429, so there is not much of a tradeoff to weigh.
What the Soundcore Rave 3/3s offers: 2 AA battery Wireless Microphones and remote control included. AI voice removal feature for Karaoke Watch for: Some upper bass and upper mids boost. Not as deep of bass as a Partybox 110/120
What the Sony GTK-XB90 offers: Deep punchy EXTRA BASS technology for party use. 3x 2.36” tweeters + 2x 7.09” woofers, built-in LED lights sync with beat. 16 hours battery claimed (9 hours real-world at moderate volume with lights). Built-in handle, portable one-box design. Fiestable plugin controls party settings and DJ effects. Three-device simultaneous Bluetooth pairing. Watch for: Bass is muddy and not deep, weird midrange peak, rolled off treble and overall strange tuning
Buy the Soundcore Rave 3/3s. It ranks higher for sound quality than the Sony GTK-XB90 and costs less, so there is no real case for the other one.
The Sony GTK-XB90 is not a sound-quality pick. It sits near the bottom of the 50 party speakers; there are better options higher up.
There is a real gap in water resistance: the Soundcore Rave 3/3s at IPX4 (splashing) against the Sony GTK-XB90, which has no water resistance.
