Short answer: the JBL Partybox 310 on measured sound quality, the Sony GTK-XB72 on price. The JBL Partybox 310 ranks #3 of 50 party speakers at $579.95. The Sony GTK-XB72 ranks #47 at $349, $230.95 cheaper.
What the JBL Partybox 310 offers: Absolute deepest bass of any battery powered speaker, most balanced sound in the class, handle and wheels are convenient. Increase treble one step in the app EQ to make it more neutral. Customizable color lighting modes. Very close to the 320 in terms of performance. Watch for: Very large.
What the Sony GTK-XB72 offers: Exceptional sound quality, powerful bass, vibrant multi-colored LED lights. ClearAudio+ and Extra Bass technology for dynamic sound. LIVE SOUND button with angled speakers and DSP for 3D sound experience. FM radio, USB, RCA inputs with Music Center app control for lighting effects and EQ. Easy to use with convenient Bluetooth and FM radio. Watch for: No deep bass at all, weird midrange peak, rolled off treble and overall strange tuning
Buy the JBL Partybox 310 when sound quality outweighs the price for you, and the Sony GTK-XB72 when the price outweighs sound quality instead.
If sound quality matters at all to you, skip the Sony GTK-XB72. 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 310 is rated at IPX4 (splashing), well ahead of the Sony GTK-XB72 at no water resistance.
