Short answer: the Soundcore Motion 300. It ranks #3 of 175 medium speakers by sound quality, rated 4.5/5, at $79.99; the Ultimate Ears Megaboom 3 ranks #108, rated 3.0/5, and costs $191.99, so there is little reason to consider the other one.
The Soundcore Motion 300 is the better-sounding, deeper-bass pick. Pretty deep bass for the small size. Its bass reaches about 50Hz before falling 10dB, against 70Hz for the Ultimate Ears Megaboom 3. Alan Ross Reviews measured it at 101dB at full volume, against 98dB for the Ultimate Ears Megaboom 3. It supports LDAC Bluetooth, which the Ultimate Ears Megaboom 3 lacks. The tradeoff: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings.
The Ultimate Ears Megaboom 3 is the longer-running choice. IP67 rated, floats, and survives drops from up to 1 meter. It is rated for 20 hours of battery against 13 for the Soundcore Motion 300. The catch: Not stereo, barely any bass.
Buy the Soundcore Motion 300. 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.

The Two Speakers In Full
Soundcore Motion 300: $79.99 Amazon $79.99 eBay
Older model: the Soundcore Motion+ (ranked lower, rated 4.4/5). See every Soundcore Motion generation.
Same family: the Soundcore Motion 100 (smaller model, ranked lower, rated 3.7/5), the Soundcore Motion X500 (larger model, rated 4.1/5) and the Soundcore Motion X600 (larger model, rated 4.3/5).
Pros: Pretty deep bass for the small size. Pocket size in a big pocket. Can be used in stereo facing you, or omnidirectional lying down. Ability to have a custom EQ for each orientation, standing, lying flat, hanging. Try the Uboom L EQs from Oluv for a more neutral sound. Measured bass extension of 50Hz (-10dB).
Cons: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings. Bassup mode is worse than Signature. Not quite as detailed or neutral as higher ranked speakers. Slight bass distortion when turned up.

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.
