Short answer: the JBL Charge 6, if you are buying new. The JBL Charge 3 ranks higher than the Ultimate Ears Megaboom 4 (#91 vs #170 of 175 medium speakers) but is discontinued; its replacement, the JBL Charge 6, is rated 4.2/5 at $119.95 and is still sold new.
The JBL Charge 3 is the better-sounding, lighter pick. Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. At 1.8 lbs (800 g) it weighs noticeably less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). It keeps a wired aux input, which the Ultimate Ears Megaboom 4 lacks. It plays in stereo from a single unit, unlike the Ultimate Ears Megaboom 4. The tradeoff: Less clarity than the JBL Flip 4.
The case for the Ultimate Ears Megaboom 4: IP67 rated, floats, and finally uses USB-C charging. It has an adjustable EQ, which the JBL Charge 3 lacks. It charges over USB-C rather than Micro USB. The tradeoff: A lot of distortion at higher volumes.
Buy the JBL Charge 6, the replacement for the discontinued JBL Charge 3; it is rated higher for sound quality than the Ultimate Ears Megaboom 4.
