Short answer: the JBL Xtreme 4 for cleaner tuning, the W-King T9 for output and battery. The Xtreme 4 offers a removable battery but is high priced. The T9 packs 80W output, 106dB max volume, a 24 hour battery, power bank function and Bluetooth 5.3 with 100ft range, though peaks in the upper mids make it sound a bit harsh.
Buy the JBL Xtreme 4 if sound quality matters more than the price. Buy the W-King T9 if the price matters more than sound quality.
There is a real gap in water resistance: the JBL Xtreme 4 at IP67 (brief submersion) against the W-King T9, which has no water resistance.
