Short answer: it depends on what you need. The Partybox 110 delivers the more neutral, bigger sound, a slight step up from the Partybox 100, but its bass is not as deep and its JBL daisychain will not talk to non-JBL speakers. The ULT Field 1 is IP67 rated, survives a 1m dunk and runs 28+ hours with ULT bass boost off, though it has an upper-midrange peak, rolled-off treble and is a much smaller speaker.
Buy the JBL Partybox 110 at $379.95 for a party speaker, or the Sony ULT Field 1 at $98 for a medium speaker instead.
There is a real gap in water resistance: the Sony ULT Field 1 at IP67 (brief submersion) against the JBL Partybox 110, which has IPX4 (splashing).

JBL Partybox 110: $379.95 Amazon eBay
Newer model: the JBL Partybox Club 120, ranked higher, rated 4.5/5.
Pros: Very neutral sound, slightly better than the Partybox 100. Measured bass extension of 41Hz (-10dB).
Cons: Bass isn’t as deep as the Partybox 100. Just as loud and slightly deeper than a Stormbox Blast which is way smaller with better sound. Increase treble one step in the app to make it more neutral.
