Short answer: the Sony ULT Field 3. It ranks #57 of 134 medium speakers at $148; the Ultimate Ears Megaboom 3 ranks #82 and costs $163, so there is not much of a tradeoff to weigh.
On the Sony ULT Field 3 side: IP67 rated, dustproof and water resistant. The catch: Sounds a bit hollow, a bit boosted in the treble.
The case for the Ultimate Ears Megaboom 3: IP67 rated, floats, and survives drops from up to 1 meter. Set against that: Not stereo, barely any bass.
Buy the Sony ULT Field 3 if the ranking matters more than the price. Buy the Ultimate Ears Megaboom 3 if the price matters more than the ranking.

Ultimate Ears Megaboom 3: $163 Amazon
Pros: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life - about double most speakers this size.
Cons: Not stereo, barely any bass. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2018. Not technically a 360 speaker, only front and rear.
