Short answer: the Ultimate Ears Epicboom for portability and battery, though neither ranks well in its class. It runs 17 hours on USB-C, the first UE portable with that connector, is IP67 rated and floats, uses mostly recycled fabric and plastic, and is called the large best-sounding UE portable that still feels portable. Its bass is not very deep for the size and it distorts around 70-80% on bass thuds, while the Dali is called horribly overpriced. Both are rated below 3.0/5 among the 105 large speakers; for better sound, the JBL Xtreme 5 ranks #2 at $399.95.
Buy the Ultimate Ears Epicboom. It is rated higher for sound quality than the DALI Katch G2 and costs less, which makes it the one to get unless you need something the other one does better.
If battery life is a priority, the DALI Katch G2 is rated for 30 hours versus 17 hours for the Ultimate Ears Epicboom.
