Short answer: the Soundcore 3/Soundcore Select 2. It ranks #54 of 136 medium speakers by sound quality at $49.99; the Ultimate Ears Megaboom 3 ranks #83 and costs $163, so there is not much of a tradeoff to weigh.
What the Soundcore 3/Soundcore Select 2 offers: Good battery life - 20+ hours on a charge. IPX7 rated. PartyCast mode links multiple speakers; app EQ presets. Watch for: A little less bass than similar size speakers.
What the Ultimate Ears Megaboom 3 offers: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life - about double most speakers this size. Watch for: Not stereo, barely any bass. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2018. Not technically a 360 speaker, only front and rear.
