Short answer: the Soundcore Rave 3S. It ranks #19 of 49 party speakers by sound quality (rated 3.8/5) at $349.99 and is still sold new; the Sony GTK-XB90 ranks #45 (rated 2.3/5) and is discontinued, so it is only an option used.
The Soundcore Rave 3S is the better-sounding, lighter choice. 2 AA battery Wireless Microphones and remote control included. At 21.6 lbs (9.8 kg) it weighs noticeably less than the Sony GTK-XB90 at 30.9 lbs (14 kg). It is rated IPX4, while the Sony GTK-XB90 has no water resistance. It has an adjustable EQ, which the Sony GTK-XB90 lacks. Watch for: Some upper bass and upper mids boost.
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 12 for the Soundcore Rave 3S. It supports LDAC Bluetooth, which the Soundcore Rave 3S lacks. It plays in stereo from a single unit, unlike the Soundcore Rave 3S. The tradeoff: Bass is muddy and not deep, weird midrange peak, rolled off treble and overall strange tuning.
Buy the Soundcore Rave 3S. It is rated higher for sound quality, and the Sony GTK-XB90 is discontinued, so it is only available used.
