Short answer: the B&O Beosound A1 2nd gen, if you are buying new. The Minirig 3 measures as well as it (#8 vs #11 of 182 medium speakers, 4.3/5 vs 4.3/5) but is discontinued, so only consider it used; the B&O Beosound A1 2nd gen is still sold new at $395. The Minirig 3’s replacement, the Minirig 4, is rated 4.3/5 at $229.95.
The Minirig 3 is the louder, longer-running choice. A compact, loud speaker with natural sound, a very long battery, and an optional add on subwoofer, now discontinued. Alan Ross Reviews measured it at 105dB at full volume, against 93dB for the B&O Beosound A1 2nd gen. It is rated for 30 hours of battery against 18 for the B&O Beosound A1 2nd gen. It keeps a wired aux input, which the B&O Beosound A1 2nd gen lacks. The tradeoff: Calls itself splash resistant and has no official water rating.
The B&O Beosound A1 2nd gen is the tougher pick. A premium waterproof puck speaker with balanced sound, a built in strap, and a long battery for travel. It is rated IP67 against Splash resistant for the Minirig 3. It supports aptX Adaptive Bluetooth, which the Minirig 3 lacks.
Buy the B&O Beosound A1 2nd gen new; the Minirig 3 is no longer sold new, so it only makes sense as a used find.
