Short answer: the Teufel Rockster Cross for midrange clarity, the Marshall Middleton II for bass depth. The Middleton II has very deep bass for its size and weight, but that boost drowns out the midrange, with a dip around 200Hz, a peak at 1kHz and another dip at 1.6kHz. The Rockster Cross is pretty neutral and more vocal-focused than a JBL Xtreme 4, though its Outdoor mode can sound harsh from a 4kHz peak.
Buy the Teufel Rockster Cross. It is rated higher for sound quality than the Marshall Middleton II and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
Battery life favors the Marshall Middleton II: rated for 30 hours against 16 hours for the Teufel Rockster Cross.

Teufel Rockster Cross: $249.99 Amazon eBay
Newer model: the Teufel Rockster Cross 2, ranked higher, rated 4.2/5.
Pros: Pretty neutral frequency response. More vocal/midrange-focused than the JBL Xtreme 4, thanks to a larger mid/bass driver: better suited to rock and jazz. Nicer upper-bass detail than the JBL Xtreme 4. Punchy, well-controlled bass that suits rock music, unlike the Soundcore Boom 2 Plus’s overboosted, uncontrolled bass even at stock tuning. Clear, detailed audio with good vocal presence and solid Bluetooth codec support even a couple years after release. Measured bass extension of 51Hz (-10dB).
Cons: Outdoor mode can sound somewhat harsh due to the 4kHz peak. Not as deep or full-sounding in the bass as the JBL Xtreme 4.
