Short answer: the B&O Beosound A1 2nd gen. It ranks #10 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.
What the B&O Beosound A1 2nd gen gets right: More neutral than the first A1. The catch: Not stereo.
On the KEF Muo gen2 side: KEF seemed to have fixed the rolled off treble and overall balance. The catch: Lacking deeper bass.
Buy the B&O Beosound A1 2nd gen if the ranking matters more than the price. Buy the KEF Muo gen2 if the price matters more than the ranking.
