Short answer: the Boat Stone 350/352/358, if you are buying new. The JBL Charge 4 ranks higher than it (#56 vs #130 of 150 medium speakers, 3.5/5 vs 2.3/5) but is discontinued, so only consider it used; the Boat Stone 350/352/358 is still sold new.
Why pick the JBL Charge 4: Doubles as a power bank for charging phones/tablets. The tradeoff: Not stereo.
What the Boat Stone 350/352/358 does well: 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 new; the JBL Charge 4 is no longer sold new, so it only makes sense as a used find.
