Short answer: the Minirig 4. It ranks #6 of 150 medium speakers by sound quality, rated 4.3/5, at $229.95. The JBL Charge 4 ranks #56, rated 3.5/5, at $94.99, $134.96 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the Minirig 4: Modular, can easily attach a subwoofer. Watch for: Calls itself splash resistant and has no official water rating.
What the JBL Charge 4 does well: Doubles as a power bank for charging phones/tablets. Watch for: Not stereo.
One note: the JBL Charge 4 is discontinued, but it still ranks #56 of 150 medium speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the Minirig 4. It is rated higher for sound quality, and the $134.96 you would save on the JBL Charge 4 does not close the gap.
There is a real gap in water resistance: the JBL Charge 4 at IPX7 (brief submersion) against the Minirig 4, which has Splash resistant (splashing).
