Short answer: the Sony SRS-XP700. It ranks #17 of 50 party speakers by sound quality at $398; the Sony GTK-XB90 ranks #46 and costs $429, so there is not much of a tradeoff to weigh.
What the Sony SRS-XP700 offers: Dual 6.69” woofers, multi-tweeter X-Balanced Speaker Units with rear tweeter for 360 effect. Exceptional 25-hour battery (18-22 hours real-world with LEDs). IPX4 splash-resistant. MEGA BASS for deep punchy sound. Karaoke (mic + guitar inputs), LED lights with stroboscopic effect. Sony Music App integration for microphone control and advanced settings. Watch for: Weird midrange peak. Slightly less loud than a Partybox 310. Bass not as deep as a Partybox 310/300/110/100.
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 Sony SRS-XP700. It ranks higher for sound quality than the Sony GTK-XB90 and costs less, so there is no real case for the other one.
Skip the Sony GTK-XB90 if sound quality matters to you. It ranks near the bottom of the 50 party speakers.
Battery life favors the Sony SRS-XP700: rated for 25 hours against 16 hours for the Sony GTK-XB90.
