Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Motion 100 is the better pick: it ranks #45 of 175 medium speakers by sound quality (rated 3.7/5), against #84 (rated 3.3/5) for the Sony XB23. If you want one new, the Sony ULT Field 1 replaces the Sony XB23 and is rated 3.1/5 at $138.
The Soundcore Motion 100 is the better-sounding, tougher option. It is rated IPX7 against IPX4 for the Sony XB23. The tradeoff: Not very deep bass, slight distortion.
What the Sony XB23 does well: Reasonably neutral. The catch: Bass drops off a ton at high levels.
Buy the Soundcore Motion 100 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Sony ULT Field 1, which replaces the Sony XB23.

Same family: the Soundcore Motion 300 (larger model, ranked higher, rated 4.5/5), the Soundcore Motion X500 (larger model, rated 4.1/5) and the Soundcore Motion X600 (larger model, rated 4.3/5). See every Soundcore Motion generation.
Pros: Use Oluv’s EQ for the flattest response. Measured bass extension of 65Hz (-10dB).
Cons: Not very deep bass, slight distortion. Real-world battery falls well short of the 12-hour claim at higher volumes (closer to 4 hours at max). Charging takes about 5 hours; no charge-out for other devices. Discontinued and no longer sold new.
