Short answer: the KEF Muo gen2 on sound, the Tribit Stormbox Mini+ on features. The Stormbox Mini+ packs IPX7 waterproofing, app support with EQ presets and AAC, true wireless stereo, USB-C charging and a built-in mic for calls, but it is not a great sounding speaker with really weak bass. The Muo gen2 is the better-balanced option, though it too lacks deeper bass.
What the KEF Muo gen2 gets right: KEF seemed to have fixed the rolled off treble and overall balance. Set against that: Lacking deeper bass.
On the Tribit Stormbox Mini+ side: IPX7 waterproof, app support with EQ presets and AAC codec, true wireless stereo (TWS) capability, USB-C charging, built-in mic for calls. The tradeoff: Not a great sounding speaker, really weak bass.
Buy the KEF Muo gen2 if sound quality matters more than the price. Buy the Tribit Stormbox Mini+ if the price matters more than sound quality.
Battery life favors the KEF Muo gen2: rated for 24 hours against 12 hours for the Tribit Stormbox Mini+.

The Two Speakers In Full
KEF Muo gen2: $249.99 Amazon 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.
