Short answer: the Tronsmart Halo 100. It ranks #75 of 120 large speakers by sound quality, rated 3.2/5, at $109.99; the Marshall Stockwell III ranks #84, rated 3.0/5, and costs $249.99, which makes this an easy call rather than a real tradeoff.
The Tronsmart Halo 100 is the tougher pick. A loud, affordable outdoor party speaker with RGB lights, water resistance, and a USB port to charge phones. It is rated IPX7 against IP55 for the Marshall Stockwell III. The catch: Not a very smooth frequency response.
The Marshall Stockwell III is the longer-running, lighter option. 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 18 for the Tronsmart Halo 100. At 2.9 lbs (1.3 kg) it weighs much less than the Tronsmart Halo 100 at 6 lbs (2.72 kg). It supports AAC Bluetooth, which the Tronsmart Halo 100 lacks. The catch: Highs are recessed by default and need the treble control maxed to compensate, still lacking detail even then.
Buy the Tronsmart Halo 100. It is rated higher for sound quality than the Marshall Stockwell III and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
