Short answer: the Sony ULT Field 3 on measured sound quality, the JBL Grip on price. The Sony ULT Field 3 ranks #57 of 136 medium speakers at $148. The JBL Grip ranks #75 at $99.95, $48.05 cheaper.
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.
What the JBL Grip offers: Ambient light on the back with settable themes Watch for: Lacking deeper bass, definitely the worst of the JBL line until you get to the smaller clip. Not as much clarity as higher ranked speakers, rolled off highs and wavy midrange
Buy the Sony ULT Field 3 when sound quality outweighs the price for you, and the JBL Grip when the price outweighs sound quality instead.
Battery life favors the Sony ULT Field 3: rated for 24 hours against 14 hours for the JBL Grip.
