Short answer: the Bose Soundlink Revolve+ II. It ranks #52 of 175 medium speakers by sound quality, rated 3.6/5, at $299. The Sony ULT Field 3 ranks #75, rated 3.4/5, at $208, $91 cheaper, which does not close the gap in sound quality.
The Bose Soundlink Revolve+ II is the lighter pick. True 360° sound stays consistent no matter where you stand around it, unlike most portable speakers. At 2 lbs (910 g) it weighs noticeably 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 catch: Overly boosted bass, warm sounding.
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 17 for the Bose Soundlink Revolve+ II. It is rated IP67 against IP55 for the Bose Soundlink Revolve+ II. It supports LDAC Bluetooth, which the Bose Soundlink Revolve+ II lacks. The catch: Sounds a bit hollow, a bit boosted in the treble.
Buy the Bose Soundlink Revolve+ II. It is rated higher for sound quality, and saving $91 with the Sony ULT Field 3 does not make up for the sound-quality gap.

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.
