Short answer: the Soundcore Boom 2. It ranks #10 of 126 large speakers by sound quality, rated 4.5/5, at $99.99; the Zealot S79 ranks #52, rated 3.6/5, and costs $106.97, which makes this an easy call rather than a real tradeoff.
The Soundcore Boom 2 is the better-sounding, lighter option. A light, waterproof large speaker with deep bass for its size, a 24 hour battery and fun lighting. At 3.7 lbs (1.68 kg) it weighs much less than the Zealot S79 at 7.3 lbs (3.3 kg). The catch: Only a single midrange driver, so you only get stereo for the tweeters.
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 24 for the Soundcore Boom 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 Soundcore Boom 2. It is rated higher for sound quality than the Zealot S79 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
