Short answer: the Minirig Mini 2. It ranks #3 of 47 small speakers by sound quality, rated 4.4/5, at $100. The JBL Go 4 ranks #25, rated 3.2/5, at $49.95, $50.05 cheaper, which does not close the gap in sound quality.
What the Minirig Mini 2 does well: Very neutral. The catch: Calls itself splash resistant and has no official water rating.
Why pick the JBL Go 4: A little more bass than the Go 3 and they fixed the strange mids peak. Watch for: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume.
Buy the Minirig Mini 2. It is rated higher for sound quality, and saving $50.05 with the JBL Go 4 does not make up for the sound-quality gap.
If battery life is a priority, the Minirig Mini 2 is rated for 12 hours versus 7 hours for the JBL Go 4.
If water resistance matters to you, the JBL Go 4 at IP67 (brief submersion) holds up far better than the Minirig Mini 2 at Splash resistant (splashing).

Newer model: the JBL Go 5, rated 3.2/5.
Pros: A little more bass than the Go 3 and they fixed the strange mids peak. Measured bass extension of ~82Hz (-10dB).
