Short answer: the W-King D8. It ranks #57 of 105 large speakers by sound quality, rated 3.5/5, at $69.99; the Zealot S97 ranks #62, rated 3.4/5, and costs $78.62, so there is little reason to consider the other one.
The W-King D8 is the longer-running, lighter pick. Claimed 24 hours (manufacturer specified) battery life, ipx7 protection, up to 101db and stereo playback make its feature set practical for its intended room or portable use. It is rated for 24 hours of battery against 12 for the Zealot S97. At 5.4 lbs (2.43 kg) it weighs noticeably less than the Zealot S97 at 7.3 lbs (3.3 kg).
Why pick the Zealot S97: For a compact 7.3 lbs (3.3 kg) boombox, the S97 delivers unusually deep, clean-enough bass with a more sensible default balance than many inexpensive Zealot models. It links with other speakers (PartyAdd up to 100 speakers), which the W-King D8 cannot. It has an adjustable EQ, which the W-King D8 lacks. The tradeoff: It is not especially loud for its size, battery life is only a claimed 12 hours, and the bass preset can swamp the rest of the music.
Buy the W-King D8. It is rated higher for sound quality than the Zealot S97 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Zealot S97: $78.62 Amazon $78.62 eBay
Pros: For a compact 3.3kg boombox, the S97 delivers unusually deep, clean-enough bass with a more sensible default balance than many inexpensive Zealot models. It also brings IPX6 protection, aux and microSD playback, power-bank outputs, three EQ presets and PartyAdd linking.
Cons: It is not especially loud for its size, battery life is only a claimed 12 hours, and the bass preset can swamp the rest of the music. There is no app or fine-grained EQ, so the Vocal preset is the only practical way to improve the balance. It is still heavy for a speaker with this output ceiling.
