Short answer: the JBL Pulse 5. It ranks #48 of 175 medium speakers by sound quality, rated 3.7/5, at $219.99. The Sony ULT Field 1 ranks #100, rated 3.1/5, at $138, $81.99 cheaper, which does not close the gap in sound quality.
The JBL Pulse 5 is the better-sounding choice. A cool light show, though it is not synced to the music like the Pulse 2. The tradeoff: Bass does not reach as deep as others, and the plastic scratches easily.
The Sony ULT Field 1 is the lighter choice. IP67 rated, survives drops and 1m submersion. At 1.4 lbs (650 g) it weighs much less than the JBL Pulse 5 at 3.3 lbs (1.5 kg). It supports AAC Bluetooth, which the JBL Pulse 5 lacks. Watch for: Upper midrange peak, rolled off treble.
Buy the JBL Pulse 5. It is rated higher for sound quality, and the $81.99 you would save on the Sony ULT Field 1 does not close the gap.
