Short answer: the Klipsch Detroit. It ranks #76 of 115 large speakers by sound quality, rated 3.1/5, at $235.11; the Marshall Stockwell III ranks #79, rated 3.0/5, and costs $249.99, so there is little reason to consider the other one.
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 Klipsch Detroit. At 2.9 lbs (1.3 kg) it weighs much less than the Klipsch Detroit at 5.5 lbs (2.5 kg). It supports AAC Bluetooth, which the Klipsch Detroit lacks. The tradeoff: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
The Klipsch Detroit is the tougher pick. A rugged, fully waterproof stereo boombox with a long battery, fast USB-C charging, and power bank output. It is rated IP67 against IP55 for the Marshall Stockwell III. Watch for: Weird boosted upper bass, bass not very deep.
Buy the Klipsch Detroit. It is rated higher for sound quality than the Marshall Stockwell III and costs less, which makes it the one to get unless you need something the other one does better.
