Short answer: the Tribit Stormbox Flow. It ranks #62 of 175 medium speakers by sound quality, rated 3.5/5, at $79.99; the KEF Muo gen2 ranks #97, rated 3.1/5, and costs $249.99, so there is not much of a tradeoff to weigh.
The Tribit Stormbox Flow is the better-sounding option. Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). Watch for: Midrange and bass are weirdly recessed about 4db below 700Hz.
Why pick the KEF Muo gen2: KEF seemed to have fixed the rolled off treble and overall balance. It supports aptX Adaptive Bluetooth, which the Tribit Stormbox Flow lacks. It plays in stereo from a single unit, unlike the Tribit Stormbox Flow. The tradeoff: Lacking deeper bass.
Buy the Tribit Stormbox Flow. It is rated higher for sound quality than the KEF Muo gen2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Tribit Stormbox Flow: $79.99 Tribit $79.99 eBay
Same family: the Tribit Stormbox Micro 2 (smaller model, rated 4.5/5), the Tribit Stormbox Pro (larger model, ranked higher, rated 3.7/5) and the Tribit Stormbox Blast (larger model, rated 4.5/5). See every Tribit Stormbox generation.
Pros: Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). IP67 rated with a loose handle for carrying/hanging. Pairs with a second Flow for stereo; USB-C port charges your phone too. Measured bass extension of 47Hz (-10dB).
Cons: Not stereo. Midrange and bass are weirdly recessed about 4db below 700Hz. You need xbass mode for it to not sound like a clock radio with missing bass. You also can’t turn up the bass enough in the custom EQ modes to get it neutral, so it will sound bass light. Firmware 1.2.3 fixes the distortion issues with xbass mode on, but bass still sounds wobbly and uncontrolled.

KEF Muo gen2: $249.99 Amazon $249.99 eBay
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.
