Short answer: the Minirig 4 with subwoofer, if you are buying new. The Minirig 3 with subwoofer ranks higher than the Marshall Middleton (#6 vs #33 of 120 large speakers) but is discontinued; its replacement, the Minirig 4 with subwoofer, is rated 4.6/5 at $290 and is still sold new.
The Minirig 3 with subwoofer is the better-sounding, louder option. A compact speaker and subwoofer pair with very balanced sound and a long battery, now discontinued but worth buying used. Alan Ross Reviews measured it at 103dB at full volume, against 99dB for the Marshall Middleton. It is rated for 30 hours of battery against 20 for the Marshall Middleton. At 3.1 lbs (1.42 kg) it weighs noticeably less than the Marshall Middleton at 4 lbs (1.8 kg). The catch: Not stereo, app is buggy.
The Marshall Middleton is the deeper-bass, tougher pick. A waterproof stereo speaker with very deep bass for its size, a long battery, a power bank and a detachable strap. Its bass reaches about 39Hz before falling 10dB, against 47Hz for the Minirig 3 with subwoofer. It is rated IPX7 against Splash resistant for the Minirig 3 with subwoofer. It links with other speakers (Marshall Stack), which the Minirig 3 with subwoofer cannot. The catch: 5db dip at 1.7kHz and 6.3kHz.
