Short answer: the Onn XL Wireless Party Speaker. It ranks #14 of 50 party speakers by sound quality at $249; the Sony GTK-XB90 ranks #46 and costs $429, so there is not much of a tradeoff to weigh.
What the Onn XL Wireless Party Speaker offers: An exceptional value in a party speaker. Includes 2 wireless microphones. Wheels and a built-in handle for easy transport. 5 multicolor LED lighting effects. Control display on the unit. Watch for: A little bright up top, not quite as well balanced as the JBL Partybox 330.
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 Onn XL Wireless Party Speaker. 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 Onn XL Wireless Party Speaker at IPX4 (splashing) against the Sony GTK-XB90, which has no water resistance.
