Short answer: the Onn XL Wireless Party Speaker. It ranks #11 of 46 party speakers by sound quality (rated 4.1/5) at $249 and is still sold new; the Sony GTK-XB90 ranks #42 (rated 2.3/5) and is discontinued, so it is only an option used.
The Onn XL Wireless Party Speaker is the better-sounding, tougher choice. A compelling all-in-one party and karaoke package: dual 8-inch woofers, 240W claimed output, two included wireless microphones, dual mic/guitar inputs, karaoke effects and USB-A phone charging. 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: Sound favors punch and a forward/bright top end over refinement.
The Sony GTK-XB90 is the lighter option. Deep punchy EXTRA BASS technology for party use. At 30.9 lbs (14 kg) it weighs noticeably less than the Onn XL Wireless Party Speaker at 44 lbs (19.96 kg). The catch: Bass is muddy and not deep, weird midrange peak, rolled off treble and overall strange tuning.
Buy the Onn XL Wireless Party Speaker. It is rated higher for sound quality, and the Sony GTK-XB90 is discontinued, so it is only available used.

The Two Speakers In Full
Onn XL Wireless Party Speaker: $249.00 Walmart $249.00 eBay
Pros: A compelling all-in-one party and karaoke package: dual 8-inch woofers, 240W claimed output, two included wireless microphones, dual mic/guitar inputs, karaoke effects and USB-A phone charging. It plays loudly enough for backyard use and has punchy bass; owners especially like the wheels, telescoping handle and colorful light effects. At 44 lb it is still a substantial cabinet, but the trolley design makes moving it far easier than carrying it.
Cons: Sound favors punch and a forward/bright top end over refinement. Independent comparisons and owner reports find the bass less deep and the overall balance less satisfying than the JBL PartyBox 320; several consider the far-cheaper Onn Large Party gen 2 the better sound-per-dollar buy. Some owners report distortion or static at high volume, and a few report wireless-mic pairing/dropout problems. Large (30 inches tall, 44 lb) and only IPX4 splash-resistant, not a speaker to leave out in rain.
