Short answer: the Marshall Stockwell III on measured sound quality, the LG Xboom Go PL7 on price. The Marshall Stockwell III ranks #59 of 82 large speakers, rated 3.0/5, at $249.99. The LG Xboom Go PL7 ranks #75, rated 2.4/5, at $70, $179.99 cheaper.
The case for the Marshall Stockwell III: 40+ hour battery life with a user-replaceable battery, strap, sleeve and grilles. The tradeoff: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
The case for the LG Xboom Go PL7: A 1.45kg portable with IPX7 protection, a claimed 24-hour battery, aux input, speakerphone capability, stereo pairing and Wireless Party Link. The tradeoff: Independent testing finds weak low-bass and top-end extension, a narrow soundstage and uneven off-axis response.

The Two Speakers In Full
Marshall Stockwell III: $249.99 Marshall eBay
Older model: the Marshall Stockwell II (rated 4.5/5).
Pros: 40+ hour battery life with a user-replaceable battery, strap, sleeve and grilles. Doubles as a USB-C power bank. IP55 dust/water resistance. App includes parametric EQ, a Soundstage widening control, and wall/corner placement compensation. Endless-rotation control knobs.
Cons: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then. Bass tends to sound resonant and boomy, with reported frequency cancellation and phase issues on complex material that EQ doesn’t fully resolve. Oluv’s A/B testing against the outgoing Stockwell II finds the default tuning muffled and muddy enough to prefer the seven-year-old original out of the box, and output loses dynamics and bass while turning harsh well below maximum volume. No aptX support.

LG Xboom Go PL7: $70 LG eBay
Pros: A 1.45kg portable with IPX7 protection, a claimed 24-hour battery, aux input, speakerphone capability, stereo pairing and Wireless Party Link. It plays fairly loudly for its size with few obvious artifacts, and its LED-rimmed passive radiators make it a practical, fun choice for casual outdoor listening.
Cons: Independent testing finds weak low-bass and top-end extension, a narrow soundstage and uneven off-axis response. The default Sound Boost processing can make the upper mids and treble aggressive; turning it off improves balance but does not transform it into a detailed or deep-bass speaker. It has no user EQ to properly tailor the result.
