Short answer: the KEF Muo gen2 if sound quality matters most, the Tribit Stormbox 2 if price matters most. The KEF Muo gen2 ranks #97 of 175 medium speakers, rated 3.1/5, at $249.99. The Tribit Stormbox 2 ranks #105, rated 3.0/5, at $69.99, $180 cheaper.
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 2 lacks. It links with other speakers (Auracast), which the Tribit Stormbox 2 cannot. It plays in stereo from a single unit, unlike the Tribit Stormbox 2. The catch: Lacking deeper bass.
Why pick the Tribit Stormbox 2: A little better sounding than the original Tribit Stormbox, less of a rolled off treble. It keeps a wired aux input, which the KEF Muo gen2 lacks. The catch: Drivers on the side, so it will have a rolled off treble listening to it face on.
Buy the KEF Muo gen2 if sound quality is the priority over the price, or the Tribit Stormbox 2 if the price is the priority over sound quality.

The Two Speakers In Full
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.

Older model: the Tribit Stormbox (ranked lower, rated 2.8/5). See every Tribit Stormbox and Stormbox 2 generation.
Pros: A little better sounding than the original Tribit Stormbox, less of a rolled off treble. Keep Xbass on for best frequency response.
Cons: Drivers on the side, so it will have a rolled off treble listening to it face on.
