Short answer: the Sony ULT Field 3. It ranks #71 of 177 medium speakers by sound quality, rated 3.4/5, at $208. The LG Xboom Grab ranks #106, rated 3.0/5, at $100.98, $107.02 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Sony ULT Field 3 is the better-sounding choice. A rugged waterproof stereo speaker with long battery life, a detailed app EQ, a shoulder strap and a phone charging port. It supports LDAC Bluetooth, which the LG Xboom Grab lacks. It plays in stereo from a single unit, unlike the LG Xboom Grab. The catch: Sounds a bit hollow, a bit boosted in the treble.
The LG Xboom Grab is the lighter pick. A rugged waterproof speaker with elastic mounting straps, a long 20 hour battery, multipoint pairing and app room calibration. At 1.5 lbs (680 g) it weighs much less than the Sony ULT Field 3 at 2.6 lbs (1.2 kg). The catch: Bass extension not as deep as the top speakers.
Buy the Sony ULT Field 3. It is rated higher for sound quality, and saving $107.02 with the LG Xboom Grab does not make up for the sound-quality gap.
