Short answer: the Brane X, if you are buying new. The Minirig 3 with subwoofer measures as well as it (#6 vs #4 of 120 large speakers, 4.6/5 vs 4.6/5) but is discontinued, so only consider it used; the Brane X is still sold new at $549. The Minirig 3 with subwoofer’s replacement, the Minirig 4 with subwoofer, is rated 4.6/5 at $290.
Buy the Brane X, since the Minirig 3 with subwoofer is discontinued and only worth hunting down used.
There is a real battery-life gap here: the Minirig 3 with subwoofer is rated for 30 hours, the Brane X only 12 hours.
