Short answer: the JBL Xtreme 4 for the stronger core speaker, the Soundcore Motion X500 for compact stereo value. The Xtreme 4 has a removable battery, slightly deeper bass than the Xtreme 3 and a custom EQ, but it costs a lot and its upper-bass-to-midrange dip cannot be corrected. The X500 offers 40W of stereo from a three-driver layout with IPX7 sealing and a Spatial Dynamic mode, though it runs bright with peaks around 250Hz and a dip at 1kHz.
The case for the JBL Xtreme 4: It has a removable battery, digs slightly deeper into the bass than the Xtreme 3, and a widely-shared custom EQ can get the best out of it. The catch: it costs a lot, leans bass-boosted out of the box, has an uncorrectable dip between the upper bass and midrange that gives it an odd character, and pushes upper-mids and treble at high volume.
Buy the Soundcore Motion X500. It is rated higher for sound quality than the JBL Xtreme 4 and costs less, so only choose the other one for a particular feature it does better.
If battery life is a priority, the JBL Xtreme 4 is rated for 24 hours versus 12 hours for the Soundcore Motion X500.
