Short answer: the Zealot S97 is the bass-value pick, while the W-King T9 is the better choice when output and battery features matter. The T9 combines 80W output, a claimed 106dB maximum, a 24-hour battery, power-bank function, and Bluetooth 5.3.
Its upper-mid peaks can make loud vocals and guitars sound harsh. The extra output is useful, but it is not the speaker to choose for a smooth, relaxed tonal balance.
The S97 offers unusually deep bass and a reasonable tuning for its price, but it cannot match the T9’s loudness. That makes it better suited to close-range music than covering a busy outdoor gathering.
Buy the W-King T9 if loud playback, long battery life, and a power bank outweigh its upper-mid harshness.
Buy the Zealot S97 if maximum bass value matters more than filling a large space.
Battery life favors the W-King T9: rated for 24 hours against 12 hours for the Zealot S97.
Water resistance is not close: the Zealot S97 is rated at IPX6 (powerful water jets), well ahead of the W-King T9 at no water resistance.
