Short answer: the Marshall Tufton if sound quality matters most, the Zealot S78 if price matters most, though neither ranks well in its class. The Marshall Tufton ranks #76 of 90 boombox speakers, rated 2.4/5, at $378.99. The Zealot S78 ranks #89, rated 2.0/5, at $159.68, $219.31 cheaper. Both are rated below 3.0/5 among the 90 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $179.99.
What the Zealot S78 gets right: 120W RMS output with 150W peak power, exceptional 40-hour battery life, power bank function, IP67 waterproof, EQ with multiple modes, dual woofers with tweeters and passive radiators, MicroSD and USB playback, AUX input. The catch: Gets distorted above 50%.
Buy the Marshall Tufton if sound quality matters more than the price. Buy the Zealot S78 if the price matters more than sound quality.
If water resistance matters to you, the Zealot S78 at IP67 (brief submersion) holds up far better than the Marshall Tufton at IPX2 (light drips).

Zealot S78: $159.68 Amazon AliExpress eBay
Pros: A robust 4.4kg party speaker with claimed 120W RMS output, IP67 protection, USB-C charging, a power-bank function, aux, USB and microSD playback, TWS pairing and multiple EQ modes. Reviews find it very loud with useful bass and long claimed battery life, making it a credible choice for outdoor gatherings.
Cons: At high volume, reviews report distortion and fluctuating level, so its headline power is more useful below its maximum setting. It has no app-based EQ, and the bass and midrange refinement do not match better-established boombox speakers; assess its sound in person if tonal accuracy matters.
