Short answer: the Sony ULT Field 5 for features, not for sound quality. It is IP67 rated with a 25-hour battery, a 10-band app EQ, Party Connect for up to 100 speakers and USB-C in and out, but its bass is not as deep as others in the category and the notes call the overall sound just okay. The DALI Katch G2 is pretty neutral but loses bass after 40% volume and is called horribly overpriced.
Buy the Sony ULT Field 5. It is rated higher for sound quality than the DALI Katch G2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
