Short answer: the Soundcore Boom 2, if you are buying new. The Soundcore Motion Boom ranks higher than the Sony ULT Field 5 (#14 vs #55 of 105 large speakers) but is discontinued; its replacement, the Soundcore Boom 2, is rated 4.5/5 at $99.99 and is still sold new.
The Soundcore Motion Boom is the better-sounding, lighter choice. 30W loud bass-heavy sound, excellent budget-friendly value. At 3.3 lbs (1.5 kg) it weighs much less than the Sony ULT Field 5 at 7.3 lbs (3.3 kg). The tradeoff: Not as neutral or detailed as other top ranked speakers.
What the Sony ULT Field 5 does well: A tough 7.3 lbs (3.3 kg) portable with IP67 protection, LDAC/AAC support, aux input, a 10-band app EQ, Party Connect, USB-C power-bank output and a claimed 25-hour battery. It supports LDAC Bluetooth, which the Soundcore Motion Boom lacks. It keeps a wired aux input, which the Soundcore Motion Boom lacks. It links with other speakers (Party Connect up to 100 speakers), which the Soundcore Motion Boom cannot. The catch: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth.
Buy the Soundcore Boom 2, the replacement for the discontinued Soundcore Motion Boom; it is rated higher for sound quality than the Sony ULT Field 5.

Sony ULT Field 5: $348.00 Amazon $348.00 eBay
Older models: the Sony SRS-XB43 (ranked lower, rated 3.5/5) and the Sony SRS-XG300 (ranked lower, rated 3.1/5). See every Sony XB and ULT generation.
Same family: the Sony ULT Field 1 (smaller model, 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 3 (smaller model, rated 3.4/5), 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: A tough 3.3kg portable with IP67 protection, LDAC/AAC support, aux input, a 10-band app EQ, Party Connect, USB-C power-bank output and a claimed 25-hour battery. Reviews find it energetic and dynamic with substantial bass, enough volume for a yard, and two ULT modes that let bass-focused listeners choose a deeper or punchier presentation.
Cons: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth. Deep bass is less authoritative than the enclosure suggests, and the loud confirmation tone when pressing the ULT button is an unnecessary annoyance. Use the app EQ and audition it before buying for detail-focused music.
