Short answer: the JBL Authentics 200, which adds Wi-Fi streaming the Marshall lacks. It supports Wi-Fi with simultaneous Alexa and Google Assistant access, and reviewers rate its balanced sound close to the pricier Authentics 300; it measures 113dB at 1kHz on max volume from a smaller cabinet. The Stanmore II pairs a 5.25-inch woofer with dual midranges and dome tweeters, but Marshall has discontinued it and its 55Hz bass spec is modest.
Authentics 200 supports Wi-Fi streaming with simultaneous Alexa and Google Assistant access, rare at this size, and reviewers rate its balanced sound close to the pricier Authentics 300; it measures about 113dB at 1kHz on max volume despite its smaller cabinet. It lacks TWS pairing, an IP rating and a battery, though.
Stanmore II pairs a 5.25” woofer with dual midranges and dome tweeters in a 4.65kg cabinet with aux, RCA and optical inputs, but Marshall has discontinued it in favor of the Stanmore III, and its 55Hz bass spec is fairly modest.
Buy the JBL Authentics 200 if Wi-Fi multi-room streaming and a higher rating matter more than price. Buy the Marshall Stanmore II only if you find one discounted, since Marshall has moved on to the Stanmore III.

Marshall Stanmore II: $300 each Discontinued eBay
Newer model: the Marshall Stanmore IV. It’s likely to perform similarly, though we can’t confirm that yet.
Pros: Marshall Stanmore II uses 5.25” woofer, 2x 2” midranges, 2x 0.75” Dome tweeters. Its 4.65 kg, aux input and limited-stereo playback make it a practical option for its intended room or portable use. Measured bass extension of 55Hz (-10dB).
Cons: Bass is limited by its 55Hz specification. Discontinued.
