Short answer: the Sony XB33. It ranks #59 of 136 medium speakers by sound quality at $110; the Marshall Emberton II ranks #100 and costs $160.23, so there is little reason to consider the other one.
What the Sony XB33 offers: IP67 rated and lightweight (2.4 lb). App-controlled color LED lighting, Party Connect links up to 100 speakers. ~19 hour real-world battery without lights. Watch for: Not very loud. Upper bass peaks, midrange dip, upper midrange peaks, not very neutral. Speaker will not remain at max volume and will turn itself down automatically.
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.
Buy the Sony XB33. It ranks higher for sound quality than the Marshall Emberton II and costs less, so there is no real case for the other one.
