Short answer: the Marshall Kilburn II. It ranks #43 of 115 large speakers by sound quality, rated 3.8/5, at $219; the Marshall Stockwell III ranks #79, rated 3.0/5, and costs $249.99, so there is not much of a tradeoff to weigh.
The Marshall Stockwell III is the longer-running, lighter pick. A stylish, rugged speaker with a very long battery you can swap yourself, a detailed app EQ, and power bank charging. It is rated for 40 hours of battery against 20 for the Marshall Kilburn II. At 2.9 lbs (1.3 kg) it weighs much less than the Marshall Kilburn II at 5.5 lbs (2.49 kg).
