Short answer: the Bogasing G4. It ranks #27 of 177 medium speakers by sound quality, rated 4.0/5, at $42.49; the LG Xboom Grab ranks #106, rated 3.0/5, and costs $100.98, which makes this an easy call rather than a real tradeoff.
What the LG Xboom Grab does well: A rugged waterproof speaker with elastic mounting straps, a long 20 hour battery, multipoint pairing and app room calibration. It supports AAC Bluetooth, which the Bogasing G4 lacks. It links with other speakers (Auracast), which the Bogasing G4 cannot. It has an adjustable EQ, which the Bogasing G4 lacks. Watch for: Bass extension not as deep as the top speakers.
The Bogasing G4 is the better-sounding, deeper-bass pick. A light, affordable waterproof speaker with surprisingly strong bass for its size, solid loudness, long battery life and stereo pairing. Its bass reaches about 56Hz before falling 10dB, against 75Hz for the LG Xboom Grab. It keeps a wired aux input, which the LG Xboom Grab lacks. It plays in stereo from a single unit, unlike the LG Xboom Grab. Watch for: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music.
Buy the Bogasing G4. It is rated higher for sound quality than the LG Xboom Grab and costs less, so only choose the other one for a particular feature it does better.
