Short answer: the Minirig 4. It ranks #7 of 179 medium speakers by sound quality, rated 4.3/5, at $229.95. The Tribit Stormbox Flow ranks #58, rated 3.5/5, at $79.99, $149.96 cheaper, which does not close the gap in sound quality.
The Minirig 4 is the better-sounding pick. A small, long lasting speaker that gets loud and can add a matching subwoofer, with a 30 hour battery. It keeps a wired aux input, which the Tribit Stormbox Flow lacks. Watch for: Calls itself splash resistant and has no official water rating.
The Tribit Stormbox Flow is the deeper-bass, tougher pick. A waterproof speaker with very long battery life, a carry handle, stereo pairing and a port that charges your phone. Its bass reaches about 47Hz before falling 10dB, against 56Hz for the Minirig 4. It is rated IPX7 against Splash resistant for the Minirig 4. The tradeoff: Midrange and bass are weirdly recessed about 4db below 700Hz.
Buy the Minirig 4. It is rated higher for sound quality, and the $149.96 you would save on the Tribit Stormbox Flow does not close the gap.
