Short answer: the Turtlebox Cub, if you are buying new. The Soundcore Motion Boom ranks higher than it (#14 vs #77 of 102 large speakers, 4.5/5 vs 3.0/5) but is discontinued, so only consider it used; the Turtlebox Cub is still sold new at $330.
The Soundcore Motion Boom is the better-sounding, longer-running option. 30W loud bass-heavy sound, excellent budget-friendly value. It is rated for 24 hours of battery against 14 for the Turtlebox Cub. At 3.3 lbs (1.5 kg) it weighs noticeably less than the Turtlebox Cub at 5.3 lbs (2.4 kg). It plays in stereo from a single unit, unlike the Turtlebox Cub. Watch for: Not as neutral or detailed as other top ranked speakers.
What the Turtlebox Cub does well: A compact, cube-shaped Turtlebox at 5.3 lbs (2.4 kg) with a real two-way layout: a 4.5 inch woofer and a 1.3 inch titanium tweeter. It links with other speakers (Party Mode), which the Soundcore Motion Boom cannot. The tradeoff: The evidence so far is listening impressions from two reviews, with no side by side tests against other brands.
Buy the Turtlebox Cub if you want one new; the Soundcore Motion Boom is discontinued, so only look for it used.

Turtlebox Cub: $330.00 Amazon eBay
Pros: A compact, cube-shaped Turtlebox at 2.4 kg with a real two-way layout: a 4.5 inch woofer and a 1.3 inch titanium tweeter. Reviewers found it very loud for its size, with warm, bass-forward tuning and a bit more bass than the Turtlebox Ranger. IP67 waterproof and dustproof, crush and drop resistant, stainless steel tie-downs, a claimed 14+ hours from a 49.95Wh battery, USB-C charging with a power bank output, stereo pairing and Party Mode.
Cons: The evidence so far is listening impressions from two reviews, with no side by side tests against other brands. One reviewer found it loses bass at high volume, and it is not as loud as the full-size Turtlebox. Turtlebox’s claimed 118dB is a figure the brand’s larger speakers have not come close to at a standard one meter distance. It is also mono from one unit, and its recessed USB-C port only fits slim cable plugs.
