Short answer: the Ultimate Ears Megaboom 4, if you are buying new. The Bose Soundlink Mini ranks higher than it (#74 vs #170 of 175 medium speakers, 3.4/5 vs 2.1/5) but is discontinued, so only consider it used; the Ultimate Ears Megaboom 4 is still sold new at $200.
The Bose Soundlink Mini is the better-sounding, lighter option. Compact aluminum build feels sturdy and dense. At 1.5 lbs (680 g) it weighs much 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. Watch for: Boosted upper bass like most Bose speakers.
The Ultimate Ears Megaboom 4 is the longer-running, tougher choice. IP67 rated, floats, and finally uses USB-C charging. It is rated for 20 hours of battery against 7 for the Bose Soundlink Mini. It is rated IP67, while the Bose Soundlink Mini has no water resistance. It has an adjustable EQ, which the Bose Soundlink Mini lacks. Watch for: A lot of distortion at higher volumes.
