Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Motion Boom is the better pick: it ranks #14 of 105 large speakers by sound quality (rated 4.5/5), against #87 (rated 2.8/5) for the Ultimate Ears Megablast. If you want one new, the Soundcore Boom 2 replaces the Soundcore Motion Boom and is rated 4.5/5 at $99.99.
The Soundcore Motion Boom is the better-sounding, deeper-bass option. 30W loud bass-heavy sound, excellent budget-friendly value. Its bass reaches about 53Hz before falling 10dB, against 64Hz for the Ultimate Ears Megablast. It is rated for 24 hours of battery against 16 for the Ultimate Ears Megablast. It has an adjustable EQ, which the Ultimate Ears Megablast lacks. The catch: Not as neutral or detailed as other top ranked speakers.
The Ultimate Ears Megablast is the lighter pick. Alexa integration (Wi-Fi + Bluetooth). At 2.4 lbs (1.1 kg) it weighs noticeably less than the Soundcore Motion Boom at 3.3 lbs (1.5 kg). It keeps a wired aux input, which the Soundcore Motion Boom lacks. The catch: Bass is not very deep compared to the competition.
Buy the Soundcore Motion Boom 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 Soundcore Boom 2, which replaces the Soundcore Motion Boom.
