Short answer: the JBL Xtreme 3 for a full size class more speaker, the Sony ULT Field 3 for features and battery. The Xtreme 3 has better treble and deeper bass than the Xtreme 2 and is more balanced than the Xtreme 4. The Sony brings IP67 sealing, a 24-hour battery, a 10-band EQ and Party Connect for up to 100 speakers, though it sounds a bit hollow with boosted treble.
Buy the JBL Xtreme 3 at $329.95 if you want a large speaker. Buy the Sony ULT Field 3 at $138 if you want a medium speaker instead.
There is a real battery-life gap here: the Sony ULT Field 3 is rated for 24 hours, the JBL Xtreme 3 only 15 hours.

Sony ULT Field 3: $138.00 Amazon eBay
Older models: the Sony XB33 (ranked lower, rated 3.4/5), the Sony SRS-XE300 (ranked lower, rated 2.8/5) and the Sony SRS-XB30 (ranked lower, rated 2.6/5).
Pros: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone.
Cons: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together - turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
