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 #56 (rated 3.5/5) for the Sony SRS-XB43. 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, louder option. 30W loud bass-heavy sound, excellent budget-friendly value. Alan Ross Reviews measured it at 106dB at full volume, against 99dB for the Sony SRS-XB43. At 3.3 lbs (1.5 kg) it weighs much less than the Sony SRS-XB43 at 6.5 lbs (2.95 kg). Watch for: Not as neutral or detailed as other top ranked speakers.
What the Sony SRS-XB43 does well: Full, warm sound with deep, rich bass. It supports LDAC Bluetooth, which the Soundcore Motion Boom lacks. It keeps a wired aux input, which the Soundcore Motion Boom lacks. It links with other speakers (Party Connect up to 100 speakers), which the Soundcore Motion Boom cannot. The tradeoff: Not as loud as others in the category.
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.
