Short answer: the Marshall Emberton III, if you are buying new. The Soundcore Motion 100 ranks higher than it (#45 vs #126 of 175 medium speakers, 3.7/5 vs 2.7/5) but is discontinued, so only consider it used; the Marshall Emberton III is still sold new at $129.99.
The Soundcore Motion 100 is the better-sounding choice. It supports LDAC Bluetooth, which the Marshall Emberton III lacks. The tradeoff: Not very deep bass, slight distortion.
The Marshall Emberton III is the longer-running option. 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. It is rated for 32 hours of battery against 12 for the Soundcore Motion 100. The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Marshall Emberton III, since the Soundcore Motion 100 is discontinued and only worth hunting down used.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.

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.

Marshall Emberton III: $129.99 Amazon $129.99 eBay

Same family: the Marshall Willen II (smaller model, rated 4/5), the Marshall Middleton II (larger model, rated 4.1/5), the Marshall Stockwell III (larger model, rated 3/5) and the Marshall Kilburn III (larger model, rated 3.8/5).
Pros: 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. IP67 rated, durable rubbery build using 50% recycled plastic. Measured bass extension of 62Hz (-10dB).
