Short answer: the Soundcore Boom 3i. It ranks #27 of 136 medium speakers by sound quality at $110; the Sony SRS-XB20 ranks #94 and costs $129, which makes this an easy call rather than a real tradeoff.
What the Soundcore Boom 3i offers: Looks to be designed as a direct competitor to the Charge 5 with a very similar sound profile, warm tuned with boosted bass. Better value for the money than the Charge 5. Watch for: Not quite as good as a Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close. An earlier firmware version had some bass distortion, update your firmware in the Soundcore App
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 Soundcore Boom 3i. It ranks higher for sound quality than the Sony SRS-XB20 and costs less, which settles it without a real tradeoff to make.
Water resistance is not close: the Soundcore Boom 3i is rated at IP68 (extended submersion), well ahead of the Sony SRS-XB20 at IPX5 (water jets).
