Short answer: the Ultimate Ears Boom 3 for features and price, the Sony SRS-XB30 only as a power bank, though neither ranks well in its class. The Boom 3 is IP67 rated, floats, runs 15 hours, pairs up to 150 speakers via PartyUp and costs $64.01 less, though it is not stereo with barely any bass and recessed treble. The Sony doubles as a power bank for your phone but sounds muffled, worse than an XB20. Both are rated below 3.0/5 among the 164 medium speakers; for better sound, the Earfun Uboom L ranks #2 at $49.79.
Buy the Ultimate Ears Boom 3. It is rated higher for sound quality; the Sony SRS-XB30 is no longer sold new.
There is a real battery-life gap here: the Sony SRS-XB30 is rated for 24 hours, the Ultimate Ears Boom 3 only 15 hours.

The Two Speakers In Full
Sony SRS-XB30: $199 Discontinued eBay
Newer model: the Sony ULT Field 3, ranked higher, rated 3.4/5.
Pros: A compact 1kg portable with IPX5 splash protection, aux input, LDAC/AAC support, Sony’s app, speakerphone capability, power-bank output, stereo pairing and Party Chain linking. It reaches a useful 95dB maximum level and has a claimed 24-hour battery life at moderate volume, making it a convenient older outdoor option. Measured bass extension of 55Hz (-10dB).
Cons: Independent lab listening rates music fidelity only fair: bass has impact but is boomy and lacks the deepest notes, while the midrange can sound hazy, muffled and grainy. Its micro-USB charging and older Bluetooth 4.2 platform now feel dated, so it is best considered for features and used-market value rather than sound quality. Discontinued.

Ultimate Ears Boom 3: $134.99 Amazon eBay
Newer model: the Ultimate Ears Boom 4, ranked higher, rated 2.9/5.
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. Measured bass extension of 91Hz (-10dB).
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.
