Short answer: the Minirig 4. It ranks #7 of 177 medium speakers by sound quality (rated 4.3/5) at $229.95 and is still sold new; the Sony SRS-XB30 ranks #133 (rated 2.6/5) and is discontinued, so it is only an option used. The Sony SRS-XB30’s replacement, the Sony ULT Field 3, is rated 3.4/5 at $208.
The Minirig 4 is the better-sounding, lighter choice. A small, long lasting speaker that gets loud and can add a matching subwoofer, with a 30 hour battery. At 1.2 lbs (550 g) it weighs much less than the Sony SRS-XB30 at 2.2 lbs (1 kg). It charges over USB-C rather than Micro USB. The catch: Calls itself splash resistant and has no official water rating.
Why pick the Sony SRS-XB30: A splash resistant Sony speaker with LDAC, a power bank output, a long rated battery and Party Chain linking, now discontinued. It supports LDAC Bluetooth, which the Minirig 4 lacks. It plays in stereo from a single unit, unlike the Minirig 4. Watch for: 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.
Buy the Minirig 4. It is rated higher for sound quality, and the Sony SRS-XB30 is discontinued, so it is only available used.
