Short answer: the Sony XB23. It ranks #64 of 136 medium speakers by sound quality at $100; the Sony SRS-XB20 ranks #94 and costs $129, which makes this an easy call rather than a real tradeoff.
What the Sony XB23 offers: Reasonably neutral. IP67 rated with a strap hook for backpacks. USB-C charging; up to 12 hour battery life. Watch for: Bass drops off a ton at high levels. Reduces its own volume over time when turned to max
What the Sony SRS-XB20 offers: IPX5 rated pill shape slides easily into a bag. 12 hour battery life. Watch for: Sounds thin at higher volumes. Bass falls away quickly.
Buy the Sony XB23. It ranks higher for sound quality than the Sony SRS-XB20 and costs less, so the other one has nothing left to offer.
