Short answer: the Sony ULT Field 1. It ranks #100 of 175 medium speakers by sound quality, rated 3.1/5, at $138; the Ultimate Ears Megaboom 3 ranks #108, rated 3.0/5, and costs $191.99, which makes this an easy call rather than a real tradeoff.
The Sony ULT Field 1 is the lighter choice. IP67 rated, survives drops and 1m submersion. At 1.4 lbs (650 g) it weighs noticeably less than the Ultimate Ears Megaboom 3 at 2 lbs (925 g). It supports AAC Bluetooth, which the Ultimate Ears Megaboom 3 lacks. It charges over USB-C rather than Micro USB. The tradeoff: Upper midrange peak, rolled off treble.
The Ultimate Ears Megaboom 3 is the longer-running option. IP67 rated, floats, and survives drops from up to 1 meter. It is rated for 20 hours of battery against 12 for the Sony ULT Field 1. Watch for: Not stereo, barely any bass.
Buy the Sony ULT Field 1. It is rated higher for sound quality than the Ultimate Ears Megaboom 3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Ultimate Ears Megaboom 3: $191.99 Amazon $191.99 eBay
Newer model: the Ultimate Ears Megaboom 4, ranked lower, rated 2.1/5, released Jun 2024. See every Ultimate Ears Wonderboom, Boom and Megaboom generation.
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.
