Short answer: the Tribit Stormbox Lava. It ranks #3 of 77 large speakers by sound quality at $100; the Marshall Kilburn II ranks #36 and costs $279, so there is not much of a tradeoff to weigh.
What the Tribit Stormbox Lava offers: Fantastic bass extension. Goes deeper than the Boom 2 as seen in the linked video of sound samples. Firmware 2.0.0 is a big improvement in neutrality. Watch for: Quite heavy for the size. Some bass boost way down low. Treble and upper mids have some peaks.
What the Marshall Kilburn II offers: 20W Class D amp + dual 8W tweeters. 20+ hour battery with quick-charge (20 min charges 3 hours of play). Rugged design with leather handle and reinforced corners, IPX2 rated. Thrives with rock music. Bluetooth 5.0 with 30ft range. Watch for: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak. Very low IPX2 water rating. AC charging
Buy the Tribit Stormbox Lava. It ranks higher for sound quality than the Marshall Kilburn II and costs less, so the other one has nothing left to offer.
Water resistance is not close: the Tribit Stormbox Lava is rated at IP67 (brief submersion), well ahead of the Marshall Kilburn II at IPX2 (light drips).
