Short answer: the JBL Charge 6, if you are buying new. The JBL Charge 3 ranks higher than the Sony ULT Field 1 (#91 vs #100 of 175 medium speakers) but is discontinued; its replacement, the JBL Charge 6, is rated 4.2/5 at $119.95 and is still sold new.
The JBL Charge 3 is the longer-running pick. Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. It is rated for 20 hours of battery against 12 for the Sony ULT Field 1. It keeps a wired aux input, which the Sony ULT Field 1 lacks. It plays in stereo from a single unit, unlike the Sony ULT Field 1. Watch for: Less clarity than the JBL Flip 4.
What the Sony ULT Field 1 does well: IP67 rated, survives drops and 1m submersion. It supports AAC Bluetooth, which the JBL Charge 3 lacks. It has an adjustable EQ, which the JBL Charge 3 lacks. It charges over USB-C rather than Micro USB. Watch for: Upper midrange peak, rolled off treble.
