Short answer: the Teufel Rockster Cross for a neutral, midrange-forward sound, the Soundcore Motion Boom for value. The Cross has a pretty neutral response and a larger mid/bass driver that makes it more vocal-focused than the JBL Xtreme 4, though outdoor mode can sound harsh from a 4kHz peak and its bass is not as deep as the Xtreme 4. The Boom’s 30W bass-heavy sound is not as neutral or detailed as other top ranked speakers.
Buy the Teufel Rockster Cross, since the Soundcore Motion Boom is discontinued and only worth hunting down used.
There is a real battery-life gap here: the Soundcore Motion Boom is rated for 24 hours, the Teufel Rockster Cross only 16 hours.

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.
