Short answer: the Sony ULT Field 3, if you are buying new. The Soundcore Boost “original model” pre-2021 ranks higher than it (#14 vs #75 of 175 medium speakers, 4.2/5 vs 3.4/5) but is discontinued, so only consider it used; the Sony ULT Field 3 is still sold new at $208.
The Soundcore Boost “original model” pre-2021 is the better-sounding, lighter pick. At 1.3 lbs (590 g), Soundcore Boost “original model” pre-2021 combines 1.75” x 2 active drivers + passive radiator with Bluetooth and aux. At 1.3 lbs (590 g) it weighs much less than the Sony ULT Field 3 at 2.6 lbs (1.2 kg). It keeps a wired aux input, which the Sony ULT Field 3 lacks. The tradeoff: Careful placement is still important for balanced bass.
The Sony ULT Field 3 is the longer-running, tougher choice. IP67 rated, dustproof and water resistant. It is rated for 24 hours of battery against 12 for the Soundcore Boost “original model” pre-2021. It is rated IP67 against IPX5 for the Soundcore Boost “original model” pre-2021. It supports LDAC Bluetooth, which the Soundcore Boost “original model” pre-2021 lacks. The tradeoff: Sounds a bit hollow, a bit boosted in the treble.
Buy the Sony ULT Field 3, since the Soundcore Boost “original model” pre-2021 is discontinued and only worth hunting down used.

Same family: the Sony ULT Field 1 (smaller model, ranked lower, rated 3.1/5), the Sony ULT Field 7 (smaller model, rated 3.2/5), the Sony ULT Tower 10 (smaller model, rated 3.9/5), the Sony ULT Field 5 (larger model, rated 3.5/5), the Sony ULT Tower 5 (larger model, rated 4.5/5), the Sony ULT Tower 7 (larger model, rated 4.7/5), the Sony ULT Tower 9 (larger model, rated 4.2/5) and the Sony ULT Tower Max (larger model, rated 4.8/5).
Pros: 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.
Cons: 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.
