Short answer: the W-King X10-1, though neither ranks well in its class. It ranks #76 of 89 boombox speakers by sound quality, rated 2.4/5, at $143; the Zealot S78 ranks #88, rated 2.0/5, and costs $159.68, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 89 boombox speakers, and the Tribit Stormbox Blast, ranked #2 at $179.99, is a better place to start if sound quality matters.
What the W-King X10-1 does well: 70W RMS output with 120W peak power, 108dB max volume, exceptional 42-hour battery life with power bank, IPX6 waterproof, Bluetooth 5.0 with 100ft range, EQ with indoor/outdoor modes, dual subwoofers with tweeters and passive radiators, TWS stereo pairing, MicroSD and USB playback, AUX input, built-in microphone. Watch for: Rolled off treble, not much bass.
What the Zealot S78 does well: 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. The catch: At high volume, reviews report distortion and fluctuating level, so its headline power is more useful below its maximum setting.
Buy the W-King X10-1. It is rated higher for sound quality than the Zealot S78 and costs less, which makes it the one to get unless you need something the other one does better.

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.
