Short answer: the Sony ULT Field 3 on measured sound quality, the Soundcore 2 on price. The Sony ULT Field 3 ranks #75 of 175 medium speakers, rated 3.4/5, at $208. The Soundcore 2 ranks #106, rated 3.0/5, at $29.99, $178.01 cheaper.
The Sony ULT Field 3 is the better-sounding option. IP67 rated, dustproof and water resistant. It supports LDAC Bluetooth, which the Soundcore 2 lacks. It has an adjustable EQ, which the Soundcore 2 lacks. It charges over USB-C rather than Micro USB. The tradeoff: Sounds a bit hollow, a bit boosted in the treble.
The Soundcore 2 is the lighter pick. At 0.7 lbs (318 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.

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.

Soundcore 2: $29.99 Amazon $29.99 eBay
Newer model: the Soundcore 3, ranked higher, rated 3.4/5, released Jan 2021. It adds app control and adjustable EQ, but drops the aux input. See every Soundcore 2 and 3 generation.
Pros: Soundcore 2 uses 2x 38mm fullrange. Its 318 g, claimed 24 hours (Manufacturer specified) battery life, IPX7 protection, aux input and stereo playback make it a practical option for its intended room or portable use.
Cons: Its 70Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment.
