Short answer: the W-King X20 for the higher ranking, the ZZA K8 for the lower price. The W-King X20 ranks #28 of 70 boombox speakers at $249.99. The ZZA K8 ranks #47 at $40, $209.99 cheaper.
What the W-King X20 gets right: 200W RMS output with 330W peak power, 112dB max volume, exceptional 24-hour battery life with power bank, IPX6 waterproof. The catch: Rising frequency response but upper treble rolled off, 700hz and 1.2khz peaks.
On the ZZA K8 side: Completely insane value for the money. The catch: Very V curve frequency response, can be harsh in the treble range.
Buy the W-King X20 if the ranking matters more than the price. Buy the ZZA K8 if the price matters more than the ranking.

ZZA K8: $40 after clipped coupon Amazon
Pros: Completely insane value for the money. Comes with 2 metal body wireless microphones that are USB-C chargeable. Comes with Chinese labeled infrared remote control. Has voice delete function that works quite well. Adjustable microphone reverb. Pretty good build quality. The default EQ is the most balanced, the other two sound muffled.
Cons: Very V curve frequency response, can be harsh in the treble range. Treble is boosted a good +10dB. Midbass is recessed. Slight distortion issue at all volume levels due to the bass high pass filter being set too low
