Short answer: the Soundcore Select Pro. It ranks #15 of 77 large speakers by sound quality at $80; the Marshall Kilburn II ranks #36 and costs $279, so there is not much of a tradeoff to weigh.
What the Marshall Kilburn II offers: 20W Class D amp + dual 8W tweeters. Set against that: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
The case for the Soundcore Select Pro: Sounds almost exactly like the Motion Boom. The catch: Boosted bass, rolled off treble.
One note: the Soundcore Select Pro is discontinued, but it still ranks #15 of 77 large speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the Soundcore Select Pro. It ranks higher for sound quality than the Marshall Kilburn II and costs less, so there is no real case for the other one.
If water resistance matters to you, the Soundcore Select Pro at IPX7 (brief submersion) holds up far better than the Marshall Kilburn II at IPX2 (light drips).
