Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Motion 100 is the better pick: it ranks #45 of 175 medium speakers by sound quality (rated 3.7/5), against #112 (rated 2.9/5) for the Ultimate Ears Wonderboom. If you want one new, the Ultimate Ears Wonderboom 4 replaces the Ultimate Ears Wonderboom and is rated 2.9/5 at $74.50.
The Soundcore Motion 100 is the better-sounding pick. It has an adjustable EQ, which the Ultimate Ears Wonderboom lacks. It plays in stereo from a single unit, unlike the Ultimate Ears Wonderboom. It charges over USB-C rather than Micro USB. The tradeoff: Not very deep bass, slight distortion.
The Ultimate Ears Wonderboom is the lighter choice. IP67 rated and floats. At 0.9 lbs (425 g) it weighs noticeably less than the Soundcore Motion 100 at 1.3 lbs (575 g). The catch: Not stereo, barely any bass, recessed treble.
Buy the Soundcore Motion 100 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Ultimate Ears Wonderboom 4, which replaces the Ultimate Ears Wonderboom.

Soundcore Motion 100: $47 Discontinued eBay
Same family: the Soundcore Motion 300 (larger model, ranked higher, rated 4.5/5), the Soundcore Motion X500 (larger model, rated 4.1/5) and the Soundcore Motion X600 (larger model, rated 4.3/5). See every Soundcore Motion generation.
Pros: Use Oluv’s EQ for the flattest response. Measured bass extension of 65Hz (-10dB).
Cons: Not very deep bass, slight distortion. Real-world battery falls well short of the 12-hour claim at higher volumes (closer to 4 hours at max). Charging takes about 5 hours; no charge-out for other devices. Discontinued and no longer sold new.
