Short answer: the Denon Envaya DSB-250BT ranks #5 of 134 medium speakers at $250; the KEF Muo gen2 ranks #72 at $249.99. Close enough in price that the ranking gap is the deciding factor.
The case for the Denon Envaya DSB-250BT: One of the early Bluetooth speakers with excellent all-around sound quality, very neutral and great soundstage. Set against that: Expensive.
What the KEF Muo gen2 gets right: KEF seemed to have fixed the rolled off treble and overall balance. The catch: Lacking deeper bass.
One note: the Denon Envaya DSB-250BT is discontinued, but it still ranks #5 of 134 medium speakers, ahead of most of what is still sold new, so it is worth considering used.
Buy the Denon Envaya DSB-250BT if the ranking matters more than the price. Buy the KEF Muo gen2 if the price matters more than the ranking.

The Two Speakers In Full
Denon Envaya DSB-250BT: $250 Discontinued
Pros: One of the early Bluetooth speakers with excellent all-around sound quality, very neutral and great soundstage. Deep bass without distortion at high volumes. IP67 waterproof and dustproof rating. USB charging port charges mobile devices. Built-in stand on back for sturdy tilted positioning.
Cons: Expensive. Treble is rolled off. Phantom battery drain issue, would not recommend these days. Uses some stereo enhancement reverb that can sound weird to some. Not as detailed as higher ranked speakers. Discontinued.
