Short answer: the JBL Pulse 5 for better sound quality, the Sony ULT Field 3 for the lower price. The JBL Pulse 5 ranks #42 of 136 medium speakers at $199.12. The Sony ULT Field 3 ranks #57 at $148, $51.12 cheaper.
What the JBL Pulse 5 offers: Cool light show, although not synced to the music like the Pulse 2. Watch for: Not quite as deep bass as others. Plastic scratches easily.
What the Sony ULT Field 3 offers: 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. Watch for: 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.
Buy the JBL Pulse 5 if sound quality is the priority over the price, or the Sony ULT Field 3 if the price is the priority over sound quality.
There is a real battery-life gap here: the Sony ULT Field 3 is rated for 24 hours, the JBL Pulse 5 only 12 hours.
