Short answer: the Bogasing G4. It ranks #27 of 172 medium speakers by sound quality, rated 4.0/5, at $38.29; the Tribit Stormbox Flow ranks #58, rated 3.5/5, and costs $79.99, so there is not much of a tradeoff to weigh.
The Bogasing G4 is the better-sounding pick. A 1.8 lbs (0.83 kg) travel-friendly speaker with 50W output, IPX7 protection, USB-C charging, aux and microSD playback, LC3 Bluetooth and TWS pairing. It keeps a wired aux input, which the Tribit Stormbox Flow lacks. It plays in stereo from a single unit, unlike the Tribit Stormbox Flow. Watch for: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music.
The Tribit Stormbox Flow is the deeper-bass, lighter choice. Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). Its bass reaches about 47Hz before falling 10dB, against 56Hz for the Bogasing G4. At 1.4 lbs (657 g) it weighs noticeably less than the Bogasing G4 at 1.8 lbs (830 g). It supports AAC Bluetooth, which the Bogasing G4 lacks. The catch: Midrange and bass are weirdly recessed about 4db below 700Hz.
Buy the Bogasing G4. It is rated higher for sound quality than the Tribit Stormbox Flow and costs less, so only choose the other one for a particular feature it does better.
