Short answer: the Harman Kardon Citation 200. It ranks #13 of 77 large speakers by sound quality at $130; the Ultimate Ears Epicboom ranks #57 and costs $213.41, which makes this an easy call rather than a real tradeoff.
What the Harman Kardon Citation 200 offers: Deeper bass than any Onyx. Watch for: 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 Ultimate Ears Epicboom offers: 17 hour battery with USB-C charging (first UE portable with USB-C). IP67 rating, floats in water. Made mostly from recycled fabric and plastic. Large best-sounding UE portable that still feels portable. 180ft Bluetooth range. Watch for: Not very deep bass for the size. Gets distorted at around 70-80% with bass thuds.
Buy the Harman Kardon Citation 200. It ranks higher for sound quality than the Ultimate Ears Epicboom and costs less, so there is no real case for the other one.
Battery life favors the Ultimate Ears Epicboom: rated for 17 hours against 8 hours for the Harman Kardon Citation 200.
If water resistance matters to you, the Ultimate Ears Epicboom at IPX7 (brief submersion) holds up far better than the Harman Kardon Citation 200 at IPX4 (splashing).
