Short answer: the EarFun Uboom L. It ranks #2 of 177 medium speakers by sound quality, rated 4.6/5, at $49.79; 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.
The EarFun Uboom L is the better-sounding, deeper-bass pick. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. 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: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
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 links with other speakers (Auracast), which the EarFun Uboom L cannot. Watch for: Bass extension not as deep as the top speakers.
Buy the EarFun Uboom L. It is rated higher for sound quality than the LG Xboom Grab and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
