Short answer: the Sonos Roam. It ranks #72 of 136 medium speakers by sound quality at $175; the KEF Muo gen2 ranks #73 and costs $249.99, so there is not much of a tradeoff to weigh.
The case for the Sonos Roam: Very neutral. The tradeoff: Bass extension isn’t very good.
What the KEF Muo gen2 offers: KEF seemed to have fixed the rolled off treble and overall balance. Watch for: Lacking deeper bass.
Buy the Sonos Roam. It ranks higher for sound quality than the KEF Muo gen2 and costs less, so there is no real case for the other one.
If battery life is a priority, the KEF Muo gen2 is rated for 24 hours versus 10 hours for the Sonos Roam.

KEF Muo gen2: $249.99 Amazon
Pros: KEF seemed to have fixed the rolled off treble and overall balance
Cons: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.
