Short answer: the Soundcore Boom 3i on measured sound quality, the Ultimate Ears Wonderboom on price. The Soundcore Boom 3i ranks #27 of 136 medium speakers at $110. The Ultimate Ears Wonderboom ranks #87 at $79, $31 cheaper.
What the Soundcore Boom 3i offers: Looks to be designed as a direct competitor to the Charge 5 with a very similar sound profile, warm tuned with boosted bass. Better value for the money than the Charge 5. Watch for: Not quite as good as a Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close. An earlier firmware version had some bass distortion, update your firmware in the Soundcore App
What the Ultimate Ears Wonderboom offers: IP67 rated and floats. Compact, light, and simple to use. Watch for: Not stereo, barely any bass, recessed treble. Dip at 9khz. Low mid bass distortion. Not technically a 360 speaker, only front and rear.
Buy the Soundcore Boom 3i when sound quality outweighs the price for you, and the Ultimate Ears Wonderboom when the price outweighs sound quality instead.
Battery life favors the Soundcore Boom 3i: rated for 16 hours against 10 hours for the Ultimate Ears Wonderboom.
