Short answer: the Marshall Kilburn II. It ranks #39 of 82 large speakers by sound quality, rated 3.8/5, at $279. The LG PN7 ranks #68, rated 2.7/5, at $150, $129 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the Marshall Kilburn II: 20W Class D amp + dual 8W tweeters. The tradeoff: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
Why pick the LG PN7: Exceptional 24-hour battery life, IPX7 waterproof, 106dB max volume, XBOOM remote app support, Wireless Party Link feature, stereo capable, USB-C charging, built-in microphone. The tradeoff: No deep bass.
Buy the Marshall Kilburn II. It is rated higher for sound quality, and the $129 saving on the LG PN7 is not enough to make up the difference.
Water resistance is not close: the LG PN7 is rated at IPX7 (brief submersion), well ahead of the Marshall Kilburn II at IPX2 (light drips).
