Short answer: the Soundcore Boom 3i. It ranks #27 of 136 medium speakers by sound quality at $110; the Sony SRS-XE300 ranks #92 and costs $137, so there is little reason to consider the other one.
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-XE300 offers: IP67 rated. Orientation-aware playback switches to stereo when laid flat. Party Connect links up to 100 speakers; fast charging (10 min charge = ~70 min playback). Watch for: Muffled sounding, not very deep bass. Hollow sounding. Worse than a XB43
Buy the Soundcore Boom 3i. It ranks higher for sound quality than the Sony SRS-XE300 and costs less, which settles it without a real tradeoff to make.
If battery life is a priority, the Sony SRS-XE300 is rated for 24 hours versus 16 hours for the Soundcore Boom 3i.
