Short answer: the Soundcore Motion 300. It ranks #3 of 175 medium speakers by sound quality, rated 4.5/5, at $79.99; the Marshall Emberton III ranks #126, rated 2.7/5, and costs $129.99, so there is little reason to consider the other one.
The Soundcore Motion 300 is the better-sounding, deeper-bass option. Pretty deep bass for the small size. Its bass reaches about 50Hz before falling 10dB, against 62Hz for the Marshall Emberton III. It supports LDAC Bluetooth, which the Marshall Emberton III lacks. The catch: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings.
The Marshall Emberton III is the longer-running choice. 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 13 for the Soundcore Motion 300. The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Soundcore Motion 300. It is rated higher for sound quality than the Marshall Emberton III and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
Soundcore Motion 300: $79.99 Amazon $79.99 eBay
Older model: the Soundcore Motion+ (ranked lower, rated 4.4/5). See every Soundcore Motion generation.
Same family: the Soundcore Motion 100 (smaller model, ranked lower, rated 3.7/5), the Soundcore Motion X500 (larger model, rated 4.1/5) and the Soundcore Motion X600 (larger model, rated 4.3/5).
Pros: Pretty deep bass for the small size. Pocket size in a big pocket. Can be used in stereo facing you, or omnidirectional lying down. Ability to have a custom EQ for each orientation, standing, lying flat, hanging. Try the Uboom L EQs from Oluv for a more neutral sound. Measured bass extension of 50Hz (-10dB).
Cons: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings. Bassup mode is worse than Signature. Not quite as detailed or neutral as higher ranked speakers. Slight bass distortion when turned up.

Marshall Emberton III: $129.99 Amazon $129.99 eBay
Older models: the Marshall Emberton II (ranked lower, rated 2.7/5) and the Marshall Emberton (ranked lower, estimated 2.6/5). See every Marshall Portable Speakers generation.
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).
Cons: Strange unnatural echo-like sound coloration, bass not as deep as competitors. Not technically a 360 speaker, only front and rear. Not very loud. Not really any different from the Marshall Emberton II except having the treble turned down a little bit.
