Short answer: the Panasonic SC-TMAX10, though neither ranks well in its class. It ranks #34 of 43 party speakers by sound quality, rated 2.6/5, at $349; the Sony GTK-XB72 ranks #40, rated 2.2/5, at $349. The price gap is small enough that the sound-quality ranking should decide it. Both are rated below 3.0/5 among the 43 party speakers; for better sound, the JBL Partybox Club 120 ranks #6 at $349.95.
What the Panasonic SC-TMAX10 does well: 300W output with 20cm woofer (dual drive) + 2x 6cm tweeters. Watch for: Not as deep bass as others in the class.
What the Sony GTK-XB72 does well: Exceptional sound quality, powerful bass, vibrant multi-colored LED lights. The catch: No deep bass at all, weird midrange peak, rolled off treble and overall strange tuning.
One note: the Panasonic SC-TMAX10 is no longer in production and isn’t widely stocked new anymore.
Buy the Panasonic SC-TMAX10. It is rated higher for sound quality than the Sony GTK-XB72 at the same price, which makes it the one to get unless you need something the other one does better.
Battery life favors the Sony GTK-XB72: rated for 23 hours against 10 hours for the Panasonic SC-TMAX10.
