Short answer: neither covers the other’s weakness, so pick the Sony ULT Field 5 for protection and the LG Xboom Bounce for its design. The ULT Field 5 at $348 against $119.99 is IP67 rated, dustproof and water resistant, but its bass is not as deep as others in the category and its sound quality overall is just okay. The Bounce has a unique spherical design of its own, with bass extension that is not as deep as the top speakers.
Buy the LG Xboom Bounce. It is rated higher for sound quality than the Sony ULT Field 5 and costs less, which makes it the one to get unless you need something the other one does better.

Sony ULT Field 5: $348.00 Amazon eBay
Older models: the Sony SRS-XB43 (ranked lower, rated 3.5/5) and the Sony SRS-XG300 (ranked lower, rated 3.1/5).
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.
