Short answer: the Marshall Stockwell II. It ranks #11 of 105 large speakers by sound quality, rated 4.5/5, at $226. The W-King D9 ranks #91, rated 2.5/5, at $71.24, $154.76 cheaper, which does not close the gap in sound quality.
The Marshall Stockwell II is the better-sounding, lighter option. Possibly the most natural sounding Marshall speaker, with excellent off-axis sound. At 3.1 lbs (1.4 kg) it weighs noticeably less than the W-King D9 at 4.4 lbs (2 kg). Watch for: Not very loud, and the added DSP reverb may annoy purists.
The W-King D9 is the louder, longer-running choice. A compact 4.4 lbs (2 kg) boombox with 60W RMS output, a claimed 106dB maximum level, a measured 47Hz -10dB bass point, IPX6 protection, power-bank output, USB-C charging, aux and microSD playback. Alan Ross Reviews measured it at 106dB at full volume, against 96dB for the Marshall Stockwell II. It is rated for 40 hours of battery against 20 for the Marshall Stockwell II. It is rated IPX6 against IPX4 for the Marshall Stockwell II. The tradeoff: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume.
Buy the Marshall Stockwell II. It is rated higher for sound quality, and the $154.76 you would save on the W-King D9 does not close the gap.

W-King D9: $71.24 Amazon $71.24 eBay
Pros: A compact 2kg boombox with 60W RMS output, a claimed 106dB maximum level, a measured 47Hz -10dB bass point, IPX6 protection, power-bank output, USB-C charging, aux and microSD playback. Long-term owners praise its loud, punchy character and useful indoor/outdoor voicing for casual outdoor listening. Measured bass extension of 47Hz (-10dB).
Cons: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume. There is no app or adjustable EQ, and its bass does not reach as deep as larger rivals, so it is better suited to energetic background music than neutral listening.
