Short answer: the Ultimate Ears Wonderboom 2, though neither ranks well in its class. It ranks #108 of 164 medium speakers by sound quality (rated 2.9/5) at $80 and is still sold new; the Bose SoundLink Color II ranks #121 (rated 2.7/5) and is discontinued, so it is only an option used. Both are rated below 3.0/5 among the 164 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #2 at $49.79.
Buy the Ultimate Ears Wonderboom 2. It is rated higher for sound quality; the Bose SoundLink Color II is no longer sold new.
Water resistance is not close: the Ultimate Ears Wonderboom 2 is rated at IP67 (brief submersion), well ahead of the Bose SoundLink Color II at IPX4 (splashing).

Ultimate Ears Wonderboom 2: $80 Amazon eBay
Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5.
Pros: IP67 rated and floats. Compact and light enough to toss in a bag. Measured bass extension of 82Hz (-10dB).
Cons: Not stereo, barely any bass, recessed treble. Slightly boosted 93Hz upper bass Dip at 9kHz. 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 2019. Not technically a 360 speaker, only front and rear.
