Short answer: the Teufel Rockster Cross 2. It ranks #22 of 82 large speakers by sound quality (rated 4.2/5); the Marshall Middleton II ranks #31 (rated 4.1/5).
The Middleton II has very deep bass for its size, reaching about 38Hz, but that bass boost drowns out the midrange, and its mids have an uneven response with a dip around 200Hz and a peak around 1kHz. It has a 5-band app EQ.
The Cross 2 sounds almost identical to the original Cross, which is fairly neutral and vocal focused with punchy bass, and its app EQ adds more bass punch.
Battery is close: 38 hours for the Cross 2, or 46 in Eco Mode, against 30 for the Middleton II. Toughness: IP67 on the Middleton II against IPX5 on the Cross 2.
Both have an aux input, a USB-C power bank and stereo pairing. The Middleton II is lighter at 1.8 kg.

The Two Speakers In Full
Teufel Rockster Cross 2: €249.99 Teufel eBay
Older model: the Teufel Rockster Cross (rated 4.2/5).
Pros: Keeps the original Rockster Cross’s sound, which was fairly neutral and vocal focused with punchy, well controlled bass, and the new Teufel Go app EQ gets noticeably more bass punch out of it than the original could manage. Claimed battery life more than doubles to 38 hours, or 46 in Eco Mode. USB-C charging with a power bank output and a built-in USB-C sound card, a 3.5mm aux input, multipoint pairing, AAC, and Party Link for a true stereo pair or up to 100 current Teufel speakers.
Cons: It uses the same drivers and amplifier as the 2018 original, so without EQ the two sound almost identical, even at maximum volume, and it measured about the same 101dB. In a direct comparison it struggles somewhat against the Soundcore Boom 2. aptX was dropped, water protection is still only IPX5 (water jets, not submersion), Party Link does not work with the original Cross, and the app’s bass and treble controls are limited. It is not sold in the US.
