Short answer: the Soundcore Boost “original model” pre-2021. It ranks #13 of 136 medium speakers by sound quality at $60; the Sony ULT Field 3 ranks #57 and costs $148, so there is not much of a tradeoff to weigh.
What the Soundcore Boost “original model” pre-2021 offers: A great sounding neutral speaker. Watch for: This old version has micro-usb charging. Only IPX5.
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 Soundcore Boost “original model” pre-2021. It ranks higher for sound quality than the Sony ULT Field 3 and costs less, so the other one has nothing left to offer.
There is a real battery-life gap here: the Sony ULT Field 3 is rated for 24 hours, the Soundcore Boost “original model” pre-2021 only 12 hours.
