Short answer: the Teufel Rockster Cross 2. It ranks #22 of 120 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 4 lbs (1.8 kg).
