Short answer: the Marshall Willen II. It ranks #11 of 62 small speakers by sound quality, rated 4.0/5, at $89.99. The Xiaomi Sound Pocket ranks #60, rated 2.3/5, at $20.99, $69 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Xiaomi Sound Pocket is the lighter pick. A truly pocketable, very cheap waterproof speaker with USB-C charging and stereo pairing, fine for hotel rooms and travel. At 0.4 lbs (200 g) it weighs much less than the Marshall Willen II at 0.8 lbs (360 g). Watch for: Its 5W driver has little real bass, and vocals can become harsh as volume rises beyond roughly 80%.
The Marshall Willen II is the better-sounding, longer-running choice. A tiny waterproof strap on speaker with balanced sound, a long battery, and app EQ that clips easily onto a bag. It is rated for 17 hours of battery against 10 for the Xiaomi Sound Pocket. The tradeoff: Not that deep of bass.
Buy the Marshall Willen II. It is rated higher for sound quality, and the $69 saving on the Xiaomi Sound Pocket is not enough to make up the difference.
