Short answer: the Megaboom 3 for battery, the Wonderboom 3 for durability per dollar. The Wonderboom 3 is IP67 rated, floats and is rated to survive a 5 ft drop onto hard surfaces, at $85.99 against $111.63. The Megaboom 3 also floats and survives drops from up to 1 meter, but the body does not give it the same 5 ft rating, and both are not stereo with barely any bass.
Buy the Ultimate Ears Megaboom 3. It is rated higher for sound quality, and the $25.64 you would save on the Ultimate Ears Wonderboom 3 does not close the gap.

The Two Speakers In Full
Ultimate Ears Megaboom 3: $111.63 Amazon eBay
Newer model: the Ultimate Ears Megaboom 4, ranked lower, rated 2.1/5.
Pros: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life: about double most speakers this size. Measured bass extension of 70Hz (-10dB).
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.
