Short answer: the Bose SoundLink Revolve (Series II). It ranks #51 of 150 medium speakers by sound quality, rated 3.6/5, at $194; the Sony ULT Field 3 ranks #64, rated 3.4/5, and costs $208, which makes this an easy call rather than a real tradeoff.
The case for the Bose SoundLink Revolve (Series II): RTINGS measured a fairly neutral sound with a balanced midrange, so vocals and lead instruments come through clearly, and excellent directivity from the 360° design for an open, even sound around the room. Watch for: RTINGS found it lacks low bass, so there’s little deep thump or rumble.
What the Sony ULT Field 3 does well: IP67 rated, dustproof and water resistant. Watch for: Sounds a bit hollow, a bit boosted in the treble.
Buy the Bose SoundLink Revolve (Series II). It is rated higher for sound quality than the Sony ULT Field 3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
Battery life favors the Sony ULT Field 3: rated for 24 hours against 13 hours for the Bose SoundLink Revolve (Series II).

The Two Speakers In Full
Bose SoundLink Revolve (Series II): $194.00 Amazon eBay
Older model: the Bose Soundlink Revolve (ranked lower, rated 3.5/5).
Pros: RTINGS measured a fairly neutral sound with a balanced midrange, so vocals and lead instruments come through clearly, and excellent directivity from the 360° design for an open, even sound around the room. In a side by side test against the Revolve+ II and B&O Beosound A1 2nd gen, several listeners preferred its clearer, less bass heavy tuning to the Revolve+ II. Up to 13 hours of battery, IP55 dust and water resistance, a built-in microphone for calls and voice assistants, and multi-connect for two devices at once.
Cons: RTINGS found it lacks low bass, so there’s little deep thump or rumble. It doesn’t get loud either: DXOMARK measured only about 73 to 74 dBA at maximum volume, against 85 to 89 dBA for speakers like the Sony SRS-XB43 in the same test, and bass compresses and pumps as you turn it up. There is no EQ in the Bose Connect app, a single unit plays mono, and it still charges over micro USB.

Sony ULT Field 3: $208.00 Amazon eBay
Older models: the Sony XB33 (ranked lower, rated 3.4/5), the Sony SRS-XE300 (ranked lower, rated 2.8/5) and the Sony SRS-XB30 (ranked lower, rated 2.6/5).
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.
