Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the Sony SRS-XB20 is the better pick: it ranks #120 of 175 medium speakers by sound quality (rated 2.8/5), against #148 (rated 2.4/5) for the Tribit Stormbox Mini. If you want one new, the Sony ULT Field 1 replaces the Sony SRS-XB20 and is rated 3.1/5 at $138. Both are rated below 3.0/5 among the 175 medium speakers, and the EarFun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
The Sony SRS-XB20 is the better-sounding option. It supports LDAC Bluetooth, which the Tribit Stormbox Mini lacks. The tradeoff: Sounds thin at higher volumes.
The Tribit Stormbox Mini is the tougher choice. IPX7 waterproof, excellent battery life (12 hours), RGB LED lighting, app support with AAC codec, true wireless stereo (TWS) capability, USB-C charging. It is rated IPX7 against IPX5 for the Sony SRS-XB20. It charges over USB-C rather than Micro USB. The tradeoff: Lacking quite a bit of bass.
Buy the Sony SRS-XB20 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 SRS-XB20.
