Short answer: the Bose Soundlink Revolve+ II for better sound quality, the Ultimate Ears Megaboom 3 for the lower price. The Bose Soundlink Revolve+ II ranks #45 of 136 medium speakers at $259. The Ultimate Ears Megaboom 3 ranks #83 at $163, $96 cheaper.
What the Bose Soundlink Revolve+ II offers: True 360° sound stays consistent no matter where you stand around it, unlike most portable speakers. Watch for: Overly boosted bass, warm sounding. Boosted mids. Rolled off treble. Only IP55.
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.
Buy the Bose Soundlink Revolve+ II if sound quality matters more than the price. Buy the Ultimate Ears Megaboom 3 if the price matters more than sound quality.
