Short answer: the Sonos Play on measured sound quality, the Ultimate Ears Megaboom 3 on price. The Sonos Play ranks #50 of 142 medium speakers at $299. The Ultimate Ears Megaboom 3 ranks #86 at $191.99, $107.01 cheaper.
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.
What the Sonos Play offers: Genuinely wide, clean stereo dispersion off-axis thanks to the two angled tweeters, holding up from the side far better than most portables. Loudness processing keeps it sounding full-bodied at low volume. 24-hour user-replaceable battery with an included wireless charging base, IP67 waterproof and dustproof, and full Sonos WiFi multi-room with AirPlay 2 on top of Bluetooth 5.3. Watch for: Bass distorts noticeably on bass-heavy tracks at default settings, and the distortion persists even after enabling Trueplay tuning and manually pulling bass back in the app. Sounds boxy and short on clarity next to cheaper competitors.
Buy the Ultimate Ears Megaboom 3 if the price is the priority over sound quality, or the Sonos Play if sound quality is the priority over the price.
