Short answer: the Bose Soundlink Mini. It ranks #56 of 136 medium speakers by sound quality at $125; the Ultimate Ears Megaboom 4 ranks #132 and costs $200, so there is not much of a tradeoff to weigh.
What the Bose Soundlink Mini offers: Compact aluminum build feels sturdy and dense. Comes with a charging cradle. Watch for: Boosted upper bass like most Bose speakers. Upper treble rolled off. Bass doesn’t go as deep as others. Failures of the mainboard are common.
What the Ultimate Ears Megaboom 4 offers: IP67 rated, floats, and finally uses USB-C charging. 20 hour battery life. ‘PartyUp’ feature syncs multiple UE speakers together. Watch for: A lot of distortion at higher volumes. Rolled off treble. Not very loud. They really screwed this up
