Short answer: the Minirig 4. It ranks #6 of 134 medium speakers at $200; the KEF Muo gen2 ranks #72 and costs $249.99, so there is not much of a tradeoff to weigh.
The case for the KEF Muo gen2: KEF seemed to have fixed the rolled off treble and overall balance. The tradeoff: Lacking deeper bass.
What the Minirig 4 gets right: Modular, can easily attach a subwoofer. The catch: Calls itself splash resistant and has no official water rating.
Buy the KEF Muo gen2 if the price matters more than the ranking. Buy the Minirig 4 if the ranking matters more than the price.
