Short answer: the Teufel Boomster Go. It ranks #7 of 47 small speakers by sound quality; the JBL Go 4 ranks #25.
The case for the JBL Go 4: A little more bass than the Go 3 and they fixed the strange mids peak. The catch: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume.
On the Teufel Boomster Go side: Pretty deep bass and quite balanced overall for the size. Watch for: Distortion becomes audible above roughly 75% volume; at max volume up close it gets unclear and tinny.
One note: the Teufel Boomster Go is discontinued, but it still ranks #7 of 47 small speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the JBL Go 4 if the price matters more than sound quality. Buy the Teufel Boomster Go if sound quality matters more than the price.

JBL Go 4: $39.95 Amazon Bhphotovideo
Pros: A little more bass than the Go 3 and they fixed the strange mids peak.
Cons: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume. Midrange can sound grainy and treble a bit sizzly; loses clarity at higher volumes.
