Short answer: the Minirig 4 if sound quality matters most, the Marshall Emberton III if price matters most. The Minirig 4 ranks #6 of 142 medium speakers at $229.95. The Marshall Emberton III ranks #102 at $160.04, $69.91 cheaper.
What the Marshall Emberton III 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. Not really any different from the Emberton II except having the treble turned down a little bit.
What the Minirig 4 offers: Modular, can easily attach a subwoofer. Finally USB-C charging. Dynamically changes sound based on forward facing or upward facing orientation Watch for: Calls itself splash resistant and has no official water rating. App is buggy. A bit expensive. Has reliability issues more often than any other speaker
