Short answer: a tie on sound quality. Both are rated 3.6/5 (#56 and #52 of 126 large speakers) at nearly the same price ($109.99 vs $106.97), so choose on features and fit.
The Tronsmart Bang 2 is the lighter pick. A loud party speaker whose bass holds up at high volume, with water resistance, a long battery, app EQ and a shoulder strap. At 5.8 lbs (2.63 kg) it weighs noticeably less than the Zealot S79 at 7.3 lbs (3.3 kg). The tradeoff: Verdicts against the Soundcore Boom 2 and the Tribit Stormbox Lava were split: Dominik Reviews preferred the Soundcore Boom 2, and several listeners found the Bang 2’s mids muffled and its highs subdued without custom EQ.
The Zealot S79 is the longer-running choice. A loud party speaker with plenty of bass, a huge battery that doubles as a power bank, lights and a shoulder strap. It is rated for 50 hours of battery against 26 for the Tronsmart Bang 2. The catch: At moderate volume the JBL Xtreme 3 is cleaner and more balanced, and one reviewer preferred the JBL Xtreme 4 in every way.
Buy the Tronsmart Bang 2 or the Zealot S79 on features: they are rated the same for sound quality at close to the same price.
