Short answer: the JBL Partybox Stage 320 for better sound quality, the Sony GTK-XB90 for the lower price. The JBL Partybox Stage 320 ranks #2 of 50 party speakers at $629.95. The Sony GTK-XB90 ranks #46 at $429, $200.95 cheaper.
What the JBL Partybox Stage 320 offers: Handle and wheels are convenient. Customizable color lighting modes. Keeps more bass than the 310 at high volume. Removable battery. Watch for: Slightly sibilant in the treble at full blast. Very large.
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 JBL Partybox Stage 320 if sound quality is the priority over the price, or the Sony GTK-XB90 if the price is the priority over sound quality.
If sound quality matters at all to you, skip the Sony GTK-XB90. It ranks near the bottom of the 50 party speakers, so look higher up the list instead.
Water resistance is not close: the JBL Partybox Stage 320 is rated at IPX4 (splashing), well ahead of the Sony GTK-XB90 at no water resistance.
