Short answer: the Soundcore Boom 3i if sound quality matters most, the W-King D320 if price matters most. The Soundcore Boom 3i ranks #27 of 136 medium speakers at $110. The W-King D320 ranks #44 at $69.99, $40.01 cheaper.
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

Buy the Soundcore Boom 3i if sound quality matters more than the price. Buy the W-King D320 if the price matters more than sound quality.
There is a real battery-life gap here: the W-King D320 is rated for 24 hours, the Soundcore Boom 3i only 16 hours.
