Short answer: the Bose Soundlink Revolve. It ranks #48 of 136 medium speakers by sound quality at $192; the Ultimate Ears Megaboom 4 ranks #132 and costs $200, which makes this an easy call rather than a real tradeoff.
What the Bose Soundlink Revolve offers: True 360° sound stays consistent no matter where you stand around it, unlike most portable speakers. Watch for: Not stereo. Strange sizzling treble, peaks and dips. Overly boosted boomy bass at 75hz.
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
Buy the Bose Soundlink Revolve. It ranks higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so the other one has nothing left to offer.
If sound quality matters at all to you, skip the Ultimate Ears Megaboom 4. It ranks near the bottom of the 136 medium speakers, so look higher up the list instead.
Battery life favors the Ultimate Ears Megaboom 4: rated for 20 hours against 12 hours for the Bose Soundlink Revolve.
There is a real gap in water resistance: the Ultimate Ears Megaboom 4 at IP67 (brief submersion) against the Bose Soundlink Revolve, which has IPX4 (splashing).
