Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Motion Boom is the better pick: it ranks #14 of 120 large speakers by sound quality (rated 4.5/5), against #95 (rated 2.7/5) for the LG PN7. If you want one new, the Soundcore Boom 2 replaces the Soundcore Motion Boom and is rated 4.5/5 at $99.99.
Buy the Soundcore Motion Boom only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Soundcore Boom 2, which replaces the Soundcore Motion Boom.
