Short answer: the Boat Stone 350/352/358, if you are buying new. The JBL Charge 3 ranks higher than it (#77 vs #130 of 150 medium speakers, 3.2/5 vs 2.3/5) but is discontinued, so only consider it used; the Boat Stone 350/352/358 is still sold new.
What the JBL Charge 3 does well: Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. Watch for: Less clarity than the Flip 4.
Why pick the Boat Stone 350/352/358: Long battery life (12 hours), IPX5 water resistant, compact and portable, sturdy build, dual passive radiators. The tradeoff: Some midrange peaks, treble slightly rolled off.
Buy the Boat Stone 350/352/358, since the JBL Charge 3 is discontinued and only worth hunting down used.
