Short answer: the Ultimate Ears Wonderboom 4. It ranks #84 of 136 medium speakers by sound quality at $59.99; the Ultimate Ears Megaboom 4 ranks #132 and costs $200, so there is not much of a tradeoff to weigh.
What the Ultimate Ears Wonderboom 4 offers: A small, IP67-rated design that floats and charges over USB-C. Watch for: Its bass does not reach as deep as the top-ranked speakers and sounds a little thuddy; beyond USB-C, it is not much of an upgrade over the Wonderboom 3.
What the Ultimate Ears Megaboom 4 offers: The Megaboom 4 adds a 20-hour battery and PartyUp support, but it is much larger and suffers from high-volume distortion and rolled-off treble.
Buy the Ultimate Ears Wonderboom 4. It ranks higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so there is no real case for the other one.
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.

Pros: IP67 rated, floats, and finally uses USB-C charging. 20 hour battery life. ‘PartyUp’ feature syncs multiple UE speakers together.
Cons: A lot of distortion at higher volumes. Rolled off treble. Not very loud. They really screwed this up
