Short answer: the W-King T9 for output and battery, the Stockwell II for natural sound. The T9 puts out 80W with a 106dB max volume, a 24-hour battery, a power bank function and Bluetooth 5.3 at 100ft range, but it peaks in the upper mids and sounds a bit harsh. The Stockwell II may be the most natural sounding Marshall speaker, though it is not stereo.
Buy the Marshall Stockwell II. It is rated higher for sound quality, and saving $118.76 with the W-King T9 does not make up for the sound-quality gap.
There is a real gap in water resistance: the Marshall Stockwell II at IPX4 (splashing) against the W-King T9, which has no water resistance.
