Short answer: the Harman Kardon Citation 200 for better sound quality, the Soundcore Select Pro for the lower price. The Harman Kardon Citation 200 ranks #13 of 77 large speakers at $130. The Soundcore Select Pro ranks #15 at $80, $50 cheaper.
The case for the Harman Kardon Citation 200: Deeper bass than any Onyx. The tradeoff: Overly boomy by default, you can short press the Bluetooth and volume down buttons simultaneously to decrease the bass, and the Bluetooth and volume up buttons simultaneously to increase it.
What the Soundcore Select Pro offers: Sounds almost exactly like the Motion Boom. Watch for: Boosted bass, rolled off treble.
Buy the Harman Kardon Citation 200 if sound quality matters more than the price. Buy the Soundcore Select Pro if the price matters more than sound quality.
If battery life is a priority, the Soundcore Select Pro is rated for 16 hours versus 8 hours for the Harman Kardon Citation 200.
If water resistance matters to you, the Soundcore Select Pro at IPX7 (brief submersion) holds up far better than the Harman Kardon Citation 200 at IPX4 (splashing).
