Short answer: the Harman Kardon Luna 2 unless you specifically want the Minirig’s balanced tuning. The Luna 2 is a single portable with a 62mm x 82mm woofer and passive radiator, tight well-controlled bass and a 12-hour battery, at $199.95 against $260. The Minirig 3 with subwoofer is not stereo, has a buggy app and TWS pairing and no official water rating, and its sub adds a second piece with no handle. The Minirig 3 with subwoofer is discontinued; its replacement is the Minirig 4 with subwoofer.

Buy the Harman Kardon Luna 2 at $199.95 for a medium speaker, or the Minirig 3 with subwoofer at $260 for a large speaker instead.
There is a real battery-life gap here: the Minirig 3 with subwoofer is rated for 30 hours, the Harman Kardon Luna 2 only 12 hours.
There is a real gap in water resistance: the Harman Kardon Luna 2 at IP67 (brief submersion) against the Minirig 3 with subwoofer, which has Splash resistant (splashing).
