Short answer: the Ultimate Ears Boom 3. It ranks #89 of 136 medium speakers by sound quality at $109; the Sony SRS-XB20 ranks #94 and costs $129, so there is not much of a tradeoff to weigh.
On the Ultimate Ears Boom 3 side: Rich and warm bass without muddying mix, crisp highs, excellent 15-hour battery life, stable Bluetooth connectivity, IP67 rated and floats, rugged fabric shell, can pair up to 150 speakers via PartyUp. Set against that: Not stereo, barely any bass, recessed treble.
The case for the Sony SRS-XB20: IPX5 rated pill shape slides easily into a bag. The tradeoff: Sounds thin at higher volumes.
Buy the Ultimate Ears Boom 3. It ranks higher for sound quality than the Sony SRS-XB20 and costs less, so there is no real case for the other one.

Ultimate Ears Boom 3: $109.00 Amazon
Pros: Rich and warm bass without muddying mix, crisp highs, excellent 15-hour battery life, stable Bluetooth connectivity, IP67 rated and floats, rugged fabric shell, can pair up to 150 speakers via PartyUp
Cons: Not stereo, barely any bass, recessed treble. 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 2021. Lots of mentions of failing batteries on amazon. Not technically a 360 speaker, only front and rear.
