Short answer: the JBL Boombox 3 on value and ruggedness, the B&O Beolit 20 on convenience. The Boombox 3 is IP67 rated, but the measurements show a mid-bass dip that leaves bass undefined, boosted bass with a peak at 700Hz and mids and treble not quite as good as the Blast’s. The Beolit 20 adds wireless phone charging and a warm sound.
Buy the JBL Boombox 3. It is rated higher for sound quality than the B&O Beolit 20 and costs less, which makes it the one to get unless you need something the other one does better.
Battery life favors the JBL Boombox 3: rated for 24 hours against 8 hours for the B&O Beolit 20.
There is a real gap in water resistance: the JBL Boombox 3 at IP67 (brief submersion) against the B&O Beolit 20, which has IPX4 (splashing).
