Short answer: the Xiaomi Sound Outdoor. It ranks #43 of 142 medium speakers by sound quality at $54.99; the Marshall Emberton II ranks #103 and costs $159.99, which makes this an easy call rather than a real tradeoff.
What the Marshall Emberton II offers: 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. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors. Not technically a 360 speaker, only front and rear. Not very loud.
What the Xiaomi Sound Outdoor offers: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. Its 597 g, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. Watch for: Its 60Hz - 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment.
Buy the Xiaomi Sound Outdoor. It ranks higher for sound quality than the Marshall Emberton II and costs less, so the other one has nothing left to offer.
There is a real battery-life gap here: the Marshall Emberton II is rated for 30 hours, the Xiaomi Sound Outdoor only 12 hours.
