Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the Soundcore Motion Boom+ is the better pick: it ranks #72 of 113 boombox speakers by sound quality (rated 2.9/5), against #107 (rated 2.1/5) for the Turtlebox. If you want one new, the Soundcore Boom 2 Plus replaces the Soundcore Motion Boom+ and is rated 3.6/5 at $169.99. Both are rated below 3.0/5 among the 113 boombox speakers; for better sound, the Tribit Stormbox Blast ranks #2 at $199.99.
The Soundcore Motion Boom+ is the better-sounding, deeper-bass option. A rugged, waterproof stereo speaker that floats, with a 20 hour battery and app EQ. Its bass reaches about 52Hz before falling 10dB, against 65Hz for the Turtlebox. At 5.3 lbs (2.4 kg) it weighs much less than the Turtlebox at 10 lbs (4.54 kg). It links with other speakers (PartyCast up to 100 speakers), which the Turtlebox cannot. Watch for: Default presets are all warm sounding with rolled off treble.
What the Turtlebox does well: A loud, waterproof and crushproof outdoor speaker with a long battery and stereo pairing with a second unit. The catch: Sounds basically identical to the later Turtlebox Gen 2 and Turtlebox Gen 3: each generation mainly added features, not sound quality.
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 Plus, which replaces the Soundcore Motion Boom+.
