Short answer: the JBL Boombox 3 Wifi if loudness is the priority; the B&O Beolit 20 for a warmer, charger-equipped speaker. The JBL is the loudest speaker in the category, but its bass is boosted. The Beolit 20 offers wireless phone charging and a warm sound.
Buy the JBL Boombox 3 Wifi. It is rated higher for sound quality than the B&O Beolit 20 and costs less, so only choose the other one for a particular feature it does better.
There is a real battery-life gap here: the JBL Boombox 3 Wifi is rated for 24 hours, the B&O Beolit 20 only 8 hours.
Water resistance is not close: the JBL Boombox 3 Wifi is rated at IP67 (brief submersion), well ahead of the B&O Beolit 20 at IPX4 (splashing).
